A preview of a new QB64 option

[SMcNeill]

If you can see in the thumbnail there, we've added a new option to the start menu for "Run only (no exe)".  This option allows you to compile your file, run it, and then cleans it off your drive when it's finished.  I saw a request somewhere about compiling to temp files, and so I took a while to come up with this for us. 

Currently it's only in my personal fork of the repo, and I've only tested it and verified that it's working as intended for Windows.  Tomorrow I'll test to get it up and going for Linux (and hopefully Mac, though I don't have a Mac to test things on), and then I'll push it into our repo and it'll be one of the features added in to our next build release.
