v1.2 Limitless Launch Arguments

- Fixed a silly bug that would've broken compatibility with dsda-doom 0.25 and onward. 

- Now allows for any launch argument you'd like to add via a handy text box (just make sure your source port supports that argument).

- Added a Close on Play toggle as requested by some.

- Included .NET dependencies for even easier use. This bad boy now works out-of-the-box on any 64-bit Windows machine, no matter how out of date your crap is.
