Add minified versions for distribution

I have used [Google's Closure Compiler](http://closure-compiler.appspot.com/home) to minify all of the scripts.

**Functionality is preserved**, so there is **no difference between non-minified and minified excluding the size and formatting.**
The header is also preserved.
You can determine if the script is minified or not if there is a .min.js at the end.

| Script Name | Non-Minifed Size | Minified Size | Size Difference |
|--------------------|---------------------------|--------------------|------------------------|
| Single Player Commands | 48.72kb | 38.478kb | 10.242kb |
| Single Player Commands Give+ | 54.378kb | 42.661kb | 11.717kb |

Minified scripts are usually only distributed for production. Imagine how hard it would be trying to read the minified versions!
