Add some utility functions for get/setting window properties. 

Move a number of ecore_x_window_prop_property_get/set calls to the new ones.
Eliminate broken (64bit arch) _ATOM_SET_... macros.
New functions should be solid as they have been in e16 for ages.
Changes in ecore_x_icccm/netwm.c have not been tested thoroughly.
