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
