UPDATE YOUR rules FOLDER!!!

- This is some Work in progress to make Wagic less "game" dependent.
This change especially is an attempt at moving away from some dangerous patents owned by some company.
It introduces "modrules.xml", a global configuration file describing dynamic settings for any given Wagic mod. It is very basic for now, but allows to customize a bit. In particular, it allows to remove the concept of shop and deck editor from the game, dynamically generate the main menu, and represent card activation with a mask rather than a rotation.
I have a sample in progress which I hope to submit in the days to come, a proof of concept (nothing fancy yet) for another type of game using these ideas, as well as a few other things I introduced recently.
In the future, I am hoping to extend modrules.xml so that it entirely describes the rules of a given card game. the other files in rules.txt will describe "extensions" to the core rules, just like they do right now, so this new file does not make them obsolete.


- Also fixed minor bugs I stumbled upon while developing
