1.Added 'face_names' method which returns list of face names:

>>> from mapnik import *
>>> for name in FontEngine.instance().face_names():
... 	print name
...
DejaVu Sans Bold
DejaVu Sans Bold Oblique

....

2. std::vector<std::string> is reflected as mapnik_.Names object

TODO: test if there are more then one face in the file
