Fixed some bugs + Added 'quit' input!

So I fixed a bunch of bugs like:

1. Input doesn't respond to anything if it has a space before or after the number.

2. The text that doesn't fit looked kinda weird.. 

And finally, If you hate my game i.e Absolutely DESPISE it, then you can type "quit", "exit" etc to leave it. Also added a whole load of easter eggs you can find ;)

Thanks for playing!
