Custom Java types

[swankjesse]

We’ve implemented some of custom proto adapters. Tracking outstanding work:

• It should be possible to nest regular protos in custom adapter protos. Preferably using the same naming scheme we use when the enclosing class is pruned.
• We should generate a new AbstractFooAdapter with methods like fromProto(String language, String country, String variant) and language(Locale locale)
• We should support selecting fields as well as types. For dates!
• We should support enums

Found a bug in this: we need to resolve imports when loading profile files. Today if a file isn’t already imported then we crash trying to validate the profile.
