Make generic wxDataViewCtrl initially usable from keyboard.

Browse Source 
This control doesn't react to the keyboard at all if it doesn't have a current
row and as it doesn't have it initially, it means that there is no way to do
anything with the control without clicking it with the mouse first.

Fix this by giving it a current row, if possible, whenever it gains focus.
