PythonQt Code

- putting classes without given package into "PythonQt.private" instead of into PythonQt directly.
- added public accessor for PythonQt module

added sharedLibrarySuffixes and callAndReturnPyObject methods

added error handling for virtual method overloads, added more global functions (qsrand etc.), added support for exec_ etc (python keyword overlap resolution), change virtual method handling, this will require code regeneration (I will do that tomorrow)

support enum values on signals as well, all tests should succeed now

added enum wrapper classes derived from python int, so that enums are distinguishable from normal python integers. This will allow better overload handling e.g. of QColor constructors in the future

fixed enum handling for static methods calls and added correct support for decorated enum detection

- added call method that does a direct call on the ObjectType
- added comments and improved docs

added support for downcasting via polymorphic handlers

changed to support dicts for variable lookup and eval

- added support for deriving CPP classes in Python and to override all public and protected virtual functions from PythonQt
- changed signal receiver code so that it can be reused for virtual method dispatch
- moved decorators completely into PythonQtClassInfo
- changed python to qt conversion so that it can work with an already allocated object (needed for return values of virtual functions
- added support for multiple inheritance and upcasting (e.g. a QWidget is automatically casted to a QPaintDevice when passed to QPainter.begin())
- removed default constructors of std decorators because they are now codegenerated
- regenerated bindings

- improved the code generator to suppot
