ImageMagick skin creator

I have seen youtube and in forms that the new skin system will DESTROY!!!!!!!!!!! TEEWORLDS because all the old skins will no longer work in the new version.  When I first saw this I thought dude its not that bad just crop out your skin into the folders.  Then I thought about how many skins there are for Teeworlds, how some people might just download the skins and not be able to do this, and how lazy we can get.  So I made the script below. 

All you have to do is place this script into the skin folder, make sure it is set as exhaustible and run it.  It will check to see if you have the folders needed for the new system and if you don't will create them for you. Then it will loop through all the .pngs in the skin folder copy them to the various folders, crop, rearrange the skin, save them, and make you a skin.skn file in your skin folder.  The developers will need to help with the skin.skn file as I did not know what to put for _hue, _sat, _lgt, _alp to not mess with the skin.

the only thing you need to do now is modify the eyes.  If your skin does not use the standard eyes then you need to modify them so that both eyes are in the one tile as the new system does not duplicate and flip them. If your skin does use the standard eyes then you will have to modify the skin.skn file and replace the last skin.png with standard.png.

I did write the lines to delete the old skin but I figured some might want to keep the old files for later.  If you want to delete the old skin then take away the '#' from '#deleteSkin
