Chris reported build errors w/ traditional makefiles.

This commit moves the 2 undefined references to BPY_interface.c and
changes things a little, hopefully fixing the problem.  I had to add a new dir,
source/blender/include/ to auto*'s Makefile.am in source/blender/python/.

Thanks Chris for the report, and Jiri, for adding a missing declaration.
