NOT TO MERGE:
This is still in process. I just wanted to put it out there for you guys to see and review the code.
This branch works ok, it drags and drops, and has the valid_move method attached to it, so running it with Inspect Element you can see on the console if an invalid move has taken place, although no test has been implemented.
I created another branch, pulled the master, and copied the code into it, but it's giving me some problems: some of the pieces give error. So, I am not sure if this would create problems with the rest of the code. :-/
