Autotiles (reject request)

Just showing, there is another easier way to do it using flags.

Dont acept this pull request since it contains privative basis.png
It has over a year since i wrote it and don't hace a clone in a linux distro to remove these files.

Known issue: autotiles SHOULD bind to animation tiles, i realized after i wrote this.

You can amend your commits and rebase to upstream master. I will explain how to setup this on Windows some day.

I'm not interested in this editor anymore, just published that code in case someone is interested on this (since code is portable for other uses) setting up vala for windows just to rebase is a waste of time, energy and hard disk space.
