Fixed issue with incorrect preview editor showing..  Files somehow lost/corrupted on merge
Merge remote-tracking branch 'remotes/gizmohd/master'
Disable the D2D rendering option for the preview (for now).
Fixed the grid/net preview control
Disabled the old schedulers, and removed a bunch of unused projects from the solution (mostly stuff that we don't even build anymore). It's still in source control if needed.

Hacked fix for the Multiple Form Opening issue... When closing forms, objects were disposed of as they should be, but when additional sequences were later opened, the objects were somehow reused, and since the objects had been disposed an ObjectDisposedException was thrown and caused the user to just wait indefinately
Merge branch 'master' of https://github.com/gizmohd/vixen.git
Prevent editor from exploding when loading a new sequence
Better fix... remove event handlers to prevent form exploding on reload
Add some null reference checking to the GDI rendering in the preview. For some reason, my window was displaying as a 0x0 window, so it couldn't get a visible graphics object to operate on, and would crash without me being able to fix it up.
3.0.8r2 changes (trivial).
