Minor visual enhancement in the combobox page of the widgets sample.

Expand the lower static box to align it with the upper one, otherwise they
look really ugly, especially under Mac.

Test wxTE_PROCESS_ENTER in the combobox page of the widgets sample.

Remove the unused "File name" checkbox in this page and put "Process Enter"
one in its place to allow toggling wxTE_PROCESS_ENTER interactively to test
whether it works as expected.

Remove "Windows only" mention from wxTE_PROCESS_ENTER documentation.

This style works for wxComboBox under GTK and OS X as well.
