* python/dbus_bindings.pyx.in:
- added new type classes for hinting to the marashaler what type
to send over the wire
- added int16 and uint16 marshalers
- Fixed a bug in the type constants that caused int32 to go out
as uint16 over the wire
* python/dbus.py: split up into different files and renamed _dbus.py
* python/__init__.py, python/_util.py, python/decorators.py,
python/exceptions.py, python/proxies.py, python/services.py,
python/types.py: new files split off from dbus.py
* python/Makefile.am: Add new files, remove dbus.py and
install all python files to <python module dir>/dbus
* python/examples/*: Added #!/usr/bin/env python to the top of
every example. Patch provided by Tatavarty Kalyan
