IsEmpty() didn't exist in all ports (notably not wxMSW) and its meaning was
unclear anyhow, so remove it even from the ports where it did exist and add
clear Is{List,Text}Empty() replacements instead.

Add a lot of tests for many wx GUI classes.
Add tests using the new wxUIActionSimulator class but disable them under OS X
as too many of them currently fail there.
Refactor the test suite to make organizing the existing tests and adding the
new ones easier.
Improve documentation using the information gathered while testing the
classes. Also update the documentation of the testing system itself.

Setting wxChoice height to its default value didn't change the height even if
the current height was different from the default. This resulted in problems
when a wxChoice was used inside a wxAuiToolBar because AUI temporarily reduces
the toolbar size to (1, 1) when docking it (thus ensuring that the height of
wxChoice is changed too) and generally didn't make sense.
Fix this by resetting the height to the default value if the value passed to
wxChoice::SetSize() is what it considers to be its default height.
Add a unit test for this bug and also add a wxChoice to AUI sample to allow
testing for wxChoice behaviour inside a wxAuiToolBar being [un]docked.
