- Fixed the crash on second time start
- Tweaked more stuff about the block

Breaking changes coming from FMOD 2.0:
- Audio[int index] changed to Audio[PARAMETER_ID index]
- Audio.Parameters removed

Newly created blocks use the initializer to set properties, allowing the user to set per-block properties

And store delegates of dynamic methods invoking constructors
Tested with the automated tests

Removed BlockIdentifiers.OWNED_BLOCKS as the original got replaced with an array
Added the correct group for each supported functional block
Removed EntityFactory property from IEntitySerializer as it is provided on deserialization
