Similar to wxNotebook but even simpler as wxSimplebook doesn't use images.
Also add wxSimplebook::Create() as the version inherited from wxBookCtrlBase
didn't _quite_ work: we need to add wxBK_TOP style to prevent asserts due to
unknown alignment in the base class when creating wxSimplebook.

Provide defaults for all properties in the spec. In XRC schema, make
all properties optional. The previously required ones are annotated as
"important" (read: should be set unless you know what you're doing), but
aren't enforced.
The code already behaved like this, so this just synchronizes the
specification with the reality.

Validating all style flags strictly would be unmaintainable mess of
verbose regular expressions that would quickly get out of sync. But we
can validate at least wxSizerItem flags, which are both stable and so
frequently used that it is worth the effort.

Incredibly, there were bugs, inaccuracies or missing content in all
three of them, but each one had its own unique problems. Fix them all
to be in sync with the implementation.
