Added a lot of stuff, read description for details.

Browse source 
Added a very small scripting language, 'G-Script' to use write commands to a file with the .gs suffix and to run It just use the newly added `run` command. For more info about the run command read further down. 

Added `loop` command - usage `loop <numberoftimetoloop> <command>` (Loops command the inputted amount of times)
Added `cat` command - usage `cat` (Prints a cute little cat to the terminal)
Added `run` command - usage `run <scriptname.gs>` (Runs  G-Script scripts)

G-Script Is still not fully Turning Complete, I'm working on It, trust me.
