Correct license (MIT/X => MIT).

The license (file) you are using seems to be MIT and not MIT/X (as [Wikipedia](http://en.wikipedia.org/wiki/MIT_License) states - referring to the distinguishing sentence). After some [research](http://www.techopedia.com/definition/3287/mit-license) I am confused, because now I see that you may intend this (similar to GNU/Linux).

This may be one of the tiniest and most useless pull requests ever, but you got me curious. ;)
