Class layout for LEGO1 classes (#43)
* Stubbed a bunch of classes and annotated them for later use. Heavily wip and more of pseudocode right now.

* Converted pseudocode into real code!

* Created a bunch more classes and added more information to exisiting ones
Did not error check, this was pushed just for reference

* More classes and implementation details. Still not checked for any errors

* Fixed code and decided on a way to handle virtual table stubs

* Some additional fixes

* More smaller fixes

* Added classes to project and made it compile

* Fixed function adresses that caused the python script to fail

* More classes and virtual function resolves. Builds and compares fine.

* Again more classes and virtual function resolves. Builds and compares fine.

* No clue, I guess forced update for line endings

* Finished up some work, compiles fine. All functions are STUB annotated to not pollute reccmp.py output.

* line ending change

* rename GetClassName/IsClass

Mirroring recent changes from master

* further conform to current master

* update project

* cleanup

* project only updates when you close msdev
