Version 1.6 released

Good news! Version 1.6 of VisualX is released!

New features include:
- DirectInput support (mostly done)
- DirectDraw primitives functions (i.e. DrawRect, etc.)
- Optimizations in some places

I'm sure that there is more than that, but it's past 1:00AM where I am, and I can't think right now.

Why am I posting an update at 1:00AM? Because we just got this project approved at SourceForge and I want to get some stuff out ASAP. So, be happy.
