Significant performance improvement to AlphaForm. Instead of having to create an unmanaged copy of a Bitmap before passing it into a DC for the UpdateLayeredWindow function, the class now exposes a Graphics object for a DC that is kept around. This means drawing can be done directly onto this buffer and passed UpdateLayeredWindow can operate immediately on the DC. This easily doubles drawing performance. Some testing reveals 5x the number of ponies can be handled compared to before!
Fixed some 'As IDisposable' casts in AnimatedImage that were being done of the wrong object and thus leaving some Bitmaps to be finalized.
Removed long since unused pony related classes from the C# project.

Converted C# component into a class library, and renamed projects accordingly.
Added some missing XMLDOC.
