AqlaSerializer v.2.0.0.96 RC1

This V2.0.0.96 release changelog:

• fixed subtypes in debug schema generation.
• added a check when RootSerializer is incorrectly used instead of base type serializer.
• root/concrete serializers will be correctly chosen for collections.

Full V2 changelog:

• Google Protocol Buffers format support is back (I've reconsidered this) - (de)serialization.
• Nested collections.
• Multi-dimensional arrays.
• Improved reference tracking (e.g. surrogate fix and referencing arrays from inside themselves).
• Improved versioning (e.g. between reference-nonreference-null-nonnull-dynamic).
• Optimizations for better output size.
• Collection subtypes (will read subtype number to create correct concrete type).
• Array types may be registered as collections and use full set of features (null support, etc) even when passed as root objects.
• Primitive types are allowed to be set to fields marked as dynamic type.
• Reference serialization will avoid using too much recursion #1.
• Possibility to specify different attribute sets for different models (see ModelId property on attributes).
• Attributes to specify behavior on collection and collection elements (and nested) separately.
• Significant performance improvements.
