Artur Sochirca d1553c63ed Improve support for TABs in wxListBox under MSW
Always set the LB_USETABSTOPS style flag to achieve behaviour more
compatible with other platforms and expand TABs to align them at tab
stops positioned at every 8 characters.

Also add MSW-specific MSWSetTabStops() method allowing to customize tab
stops.

Update the documentation and the sample to demonstrate using TABs.
