Audaspace: HUGE Refactor.

Some points of the refactor not sorted by importance:

* Fixed immutability of readers and factories (there are exceptions...)
* Fixed copy constructors and = operators
* Removed messaging system
* Removed reader types
* Added const where possible
* Using initalisers when possible
* Avoided use of pointers when possible
* Removed AUD_NEW and AUD_DELETE macros
* Removed useless NULL pointer checks
* Fixed exception catching
* Fixed some yet unknown bugs
* Lots of other stuff
