WinGui:

WinGui:
- getCliProcess(): This is now massively faster at returning the process ID of HandBrakeCLI. This means that the GUI updates it's elements far faster instead of the noticeable few seconds pause when an encode starts. This also fixes an error message that would appear if the CLI process quit before the GUI was setup.
- Code re factoring in Main.cs. Reduced the amount of code needed for a few functions.
- Combined the Encode and Queue handler. This just makes things a bit easier when other parts of the GUI need the encode process info. The new CLI handling code is not in yet.
- Added the CLI build environment to the About window
