Willian Padovani Germano 34977b8937 BPython: 
- applied Campbell Barton's patch for access to Oops location and selection of materials, mesh data and objects, slightly modified. Thanks, Campbell;
- got rid of warnings in many files, hopefully not introducing any other during the process.  Mostly this was done: 1) new EXPP_incr_ret_True/False functions were added and used instead of "Py_INCREF(Py_True/False); return Py_True/False;".  Currently at least the functions use the fact that PyTrue/False == 1/0 and use 1 and 0 to avoid the warnings. 2) Filling of certain types structs got 0's added for all not defined data and methods.  This is surely Python version specific, since these structs can change size and content at each major version number Python update.
