Vadim Zeitlin d7f19ee610 Fix spelling in comments and documentation using codespell 
Apply the utility from https://github.com/codespell-project/codespell/
to fix spelling issues in the headers under both include and interface
directories and add a file with a couple of exceptions.

The exact command line used was:

/**
@class wxTreeListCtrl
A control combining wxTreeCtrl and wxListCtrl features.
This is a multi-column tree control optionally supporting images and
checkboxes for the items in the first column.
It is currently implemented using wxDataViewCtrl internally but provides a
much simpler interface for the common use case it addresses. Thus, one of
the design principles for this control is simplicity and intentionally
doesn't provide all the features of wxDataViewCtrl. Most importantly, this
class stores all its data internally and doesn't require you to define a
custom model for it.
Instead, this controls works like wxTreeCtrl or non-virtual wxListCtrl and
allows you to simply add items to it using wxTreeListCtrl::AppendItem() and
related methods. Typically, you start by setting up the columns (you must
have at least one) by calling wxTreeListCtrl::AppendColumn() and then add
the items. While only the text of the first column can be specified when
adding them, you can use wxTreeListCtrl::SetItemText() to set the text of
the other columns.
Unlike wxTreeCtrl or wxListCtrl this control can sort its items on its own.
To allow user to sort the control contents by clicking on some column you
should use wxCOL_SORTABLE flag when adding that column to the control. When
a column with this flag is clicked, the control resorts itself using the
values in this column. By default the sort is done using alphabetical order
comparison of the items text, which is not always correct (e.g. this
doesn't work for the numeric columns). To change this you may use
SetItemComparator() method to provide a custom comparator, i.e. simply an
object that implements comparison between the two items. The treelist
sample shows an example of doing this. And if you need to sort the control
programmatically, you can call SetSortColumn() method.
Here are the styles supported by this control. Notice that using
wxTL_USER_3STATE implies wxTL_3STATE and wxTL_3STATE in turn implies
wxTL_CHECKBOX.
@beginStyleTable
@style{wxTL_SINGLE}
Single selection, this is the default.
@style{wxTL_MULTIPLE}
Allow multiple selection, see GetSelections().
@style{wxTL_CHECKBOX}
Show the usual, 2 state, checkboxes for the items in the first column.
@style{wxTL_3STATE}
Show the checkboxes that can possibly be set by the program, but not
the user, to a third, undetermined, state, for the items in the first
column. Implies wxTL_CHECKBOX.
@style{wxTL_USER_3STATE}
Same as wxTL_3STATE but the user can also set the checkboxes to the
undetermined state. Implies wxTL_3STATE.
@style{wxTL_NO_HEADER}
Don't show the column headers, that are shown by default. Notice that
this style is only available since wxWidgets 2.9.5.
@style{wxTL_DEFAULT_STYLE}
Style used by the control by default, just wxTL_SINGLE currently.
@endStyleTable
@beginEventTable{wxTreeListEvent}
@event{EVT_TREELIST_SELECTION_CHANGED(id, func)}
Process @c wxEVT_TREELIST_SELECTION_CHANGED event and notifies
about the selection change in the control. In the single selection case
the item indicated by the event has been selected and previously
selected item, if any, was deselected. In multiple selection case, the
selection of this item has just changed (it may have been either
selected or deselected) but notice that the selection of other items
could have changed as well, use wxTreeListCtrl::GetSelections() to
retrieve the new selection if necessary.
@event{EVT_TREELIST_ITEM_EXPANDING(id, func)}
Process @c wxEVT_TREELIST_ITEM_EXPANDING event notifying about
the given branch being expanded. This event is sent before the
expansion occurs and can be vetoed to prevent it from happening.
@event{EVT_TREELIST_ITEM_EXPANDED(id, func)}
Process @c wxEVT_TREELIST_ITEM_EXPANDED event notifying about
the expansion of the given branch. This event is sent after the
expansion occurs and can't be vetoed.
@event{EVT_TREELIST_ITEM_CHECKED(id, func)}
Process @c wxEVT_TREELIST_ITEM_CHECKED event notifying about
the user checking or unchecking the item. You can use
wxTreeListCtrl::GetCheckedState() to retrieve the new item state and
wxTreeListEvent::GetOldCheckedState() to get the previous one.
@event{EVT_TREELIST_ITEM_ACTIVATED(id, func)}
Process @c wxEVT_TREELIST_ITEM_ACTIVATED event notifying about
the user double clicking the item or activating it from keyboard.
@event{EVT_TREELIST_ITEM_CONTEXT_MENU(id, func)}
Process @c wxEVT_TREELIST_ITEM_CONTEXT_MENU event indicating
that the popup menu for the given item should be displayed.
@event{EVT_TREELIST_COLUMN_SORTED(id, func)}
Process @c wxEVT_TREELIST_COLUMN_SORTED event indicating that
the control contents has just been resorted using the specified column.
The event doesn't carry the sort direction, use GetSortColumn() method
if you need to know it.
