Jörg Müller 986267300b Audaspace: Moving audaspace 1.3 into extern.
Deleting the old internal audaspace.

Major changes from there are:
- The whole library was refactored to use C++11.
- Many stability and performance improvements.
- Major Python API refactor:
 - Most requested: Play self generated sounds using numpy arrays.
 - For games: Sound list, random sounds and dynamic music.
 - Writing sounds to files.
 - Sequencing API.
 - Opening sound devices, eg. Jack.
- Ability to choose different OpenAL devices in the user settings.
