Add test for coverage of SIP bindings

Not perfect, but good for a quick warning if a new class or member
has been added to the public API without Python bindings. The test
only considers the name of members, since it seems to be impossible
to test for the signature of a Python member. (So adding a new
overloaded method without bindings will still unfortunately pass).

You can avoid the test where bindings are not applicable:
- for a whole class by placing "@note not available in Python bindings"
in the class' Doxygen comments
- or by placing the @note inside a member's Doxygen comments for a
specific member

Additionally, classes which aren't included in the API docs
will not be tested.
