Petr Mrázek 5fabb4f254 NOISSUE Rough refactor of ProfilePatch and VersionFile internals.
They are now distinct classes with distinct responsibilities.

* ProfilePatch is an entry in MinecraftProfile and can hold VersionFile or Meta::Version.
* VersionFile is the basic element that holds version information loaded from JSON.
* Meta::Version is the loader class for VersionFile(s) from a server.
