Subject: Move all the QProperty related code into one compilation unit

And mark some methods as inline.

Performance is critical for our new property system. Compiling
it in one unit makes it possible for the compiler to do a much
better job at inlining and generating optimized code.

Improves performance of binding evaluations by another 20%.
