'this' in abstracts should refer to underlying type.

[EricBishton]

When referring to 'this' in abstract classes, the underlying class is actually being referred to. 'Goto', completion, etc. should work with the underlying class. Right now, in the IDE, 'this' is understood to refer to the surrounding (abstract) class. (There is a conversation about using 'self' to refer to the abstract itself.) The resolver needs to understand that 'this' can refer to another class in this instance.

Need to update the main HaxeResolver, but probably also the _handle() routine in the HaxeTypeResolver (models).
