Added some missing wxTextCtrl features to to-do list in wxX11's readme.txt

Made the wxTipDialog fonts all Swiss (TODO: use current GUI setting for
the font family)
Worked around focus anomaly by suppressing parent's FocusIn event
when child's focus is being set by clicking on it (TODO: move some of this
to SetFocus() to make it work programmatically)
