This symbol is defined for the ports that support wxCHK_3STATE style. While
most of the ports do support it, a couple still do not and having this symbol
makes it more convenient to exclude 3-state-checkbox-specific code, like in
CheckBoxTestCase.

Detect when incompatible styles are used (this required changing the value of
wxCHK_2STATE to be non-null) and sanitize the styles (after asserting) in this
case.
Put the validation code in wxCheckBoxBase instead of having slightly different
versions of it in port-specific wxCheckBox implementations.
Add a unit test checking that the expected asserts are indeed generated.

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.
