python modules bpy.app, bpy.utils are now included in docs.
C defined python module bpy.props has its docstrings extracted and written directly into sphinx docs since the C methods cant be inspected.
added docstrings to bpy.props and improved some in bpy.utils.
will update online docs tomorrow.
from bpy.app import binary_path, version, version_string, home
can add constant variables from blender here as needed (maybe functions too... bpy.app.memory_usage() ?)
