Version 0.10.2.2

I'm still working on the new rendering loop, as well as polygon-based movement rules. However, before I release that, I had to go fix some bugs that had been pointed out in the discord. 

I have also upgraded the ren'py version the pink engine is written for to 0.7.1. This doesn't change a whole lot (yet), but some of the strings for the shortcut keys had been changed since the older version of ren'py I had been developing in. This could lead to accidentally taking screenshots or opening the developer menu. 

I also cleaned up the project a little, so you no longer have a 'concept' folder full of unfinished classes lying around.
