Updated the URL for PyCrypto in the installation instructions to point to its current home. #467
"1.1-master" meant "1.1, 1.2, 1.3 and master", sorry.
The trick to Git/etc is that branches are copies. So once something is added to the "trunk" of the "tree", it will be in any version of the code released afterwards.
If you google around for "version control release branches" you'll find descriptions of how all this works.
