Bringing Titan to where it belongs: Haiku.

The code will be continually stripped of portability considerations and Windows code will be fully removed.

Titan was once functional on BeOS and much of the code for BeOS remains, however further development continued with a Windows-exclusive focus.

This means that portability has been lost. Class definitions have been altered - radically, in many cases. We are also starting without a build engine, and have selected to use Jam to create a one.
