Linux Beta1 Release

I've enabled linux support and also created a .tar.gz archive that has all the necessary Qt libraries in it to allow running it without having to install Qt. You can still install it if you want though. Right now it's built against Qt5.3.1.

There is a README file included that has the steps to get everything setup and running on linux. It's 64 bit so you'll need to be running a 64 bit version of linux. I'm currently running it on Linux Mint 17. Hopefully it should run on other distros without a problem!
