Version 2 Examples

I'm working on some examples on how to do some common things in the XnaHelpers V2 library. Right now I have an Input example for windows, I'm working on one for the Xbox. I plan to make one on File I/O and using the GuideHelper efficiently. I also plan to make some upgrades to the library, the changes will show up in the source code tab so check it out once in awhile to see if there's anything new!
