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.
