New sharing options and URL shortener on textadventures.co.u

[Alex]

I've made a few small improvements to textadventures.co.uk:

- new Facebook "like" links for each game, so you can easily share them
- set up our own URL shortener http://textga.me/ - created automatically for all uploads
- added a "Share on Twitter" link for each game which lets you easily tweet the short link

All uploads are now instantly tweeted on the @TextAdv twitter feed - http://twitter.com/textadv

Still a lot more to be done of course - I want to make it easier to manage your own games so you can easily upload new versions etc., but these new features were quick and fun...
