lego1: implement MxAutoLocker, MxTimer + dependencies

[WamWooWam]

i thought this'd be a nice, simple, small class to start with boy was i wrong

Implements MxTimer + bits needed to ensure it's generating proper code. There's a couple incomplete functions in here like MxOmni::Create as a result.

MxAutoLocker hasn't been tested for code generation yet because it's all inlined and there's nothing that uses it meaning MSVC optimises the code out.

Also has macros for MX_TRUE and MX_FALSE because otherwise you'd need to include a header like Windows.h for true/false constants.
