Update 1.0.5

- Fixed crash when mashing ESC key during game fade-in.
- Adjusted game timing issues on slower machines. Particles will still slow down but delta time for the game should keep gameplay from crawling.
- Backup save files to protect in case of crashes during saving. You may lose a little progress, but you shouldn't lose all your data if the file gets corrupted.
- F12 for screenshots. Doesn't appear to work on mac at the moment. Screenshots are saved in %LOCALAPPDATA%/Mixolumia/screenshots/
