MovieSandbox V1390 Beta released

The near final version of the UT2004 Moviesandbox is released and ready for download from the Downloads page.
There are a lot of "under the hood" fixes in this release but it also prepares Moviesandbox for the "Puppeteer" content that i will release very soon as a separate download. I also implemented graphics tablet support (in the System Menu) as requested by some of you guys.
This is basically a final release. The only things the next version will do differently is that it will allow you to export your content to the second iteration of moviesandbox, and maybe fix some bugs.

Thank you all for your input and help in creating this software!
