Added conversion to and from exponential map representation. This
representation is useful for interpolation of > 2 quaternions, or in
PD controllers.
Implementation in C functions quat_to_expmap,
quat_normalized_to_expmap, and expmap_to_quat with Python API, unit
tests and documentation.
Added Quaternion.to_exponential_map() and Quaternion(3-vector) to
Python API.

First commit to make some structure in doc/ directory.
- moved source/blender/python/doc -> doc/python_api
- moved source/gameengine/PyDoc/*.rst -> doc/python_api/rst
- modified accordingly sphinx_doc_gen.py and sphinx_doc_gen.sh
(later on I'll try alternative/ scripts by neXyon as promised :)
