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 --------- Co-authored-by: Cydra <cydra95@gmail.com> Co-authored-by: itsmattkc <34096995+itsmattkc@users.noreply.github.com>
