Added build min and build debug tasks to grunt
Added build min and build debug tasks to grunt

Now we can execute:
- grunt build: will generate both minified and not minified build files.
You can call it with targets "min" and "debug". Example: grunt build:min
- grunt buildMin: will generate minified version
- grunt buildDebug: not minified
