1.3.4 hotfix — Slaves of Magic Steam update #1020320

Hello everyone! This is a hotfix primarily to solve a video card shader issue (that is most prominently causing the missing text on the main menu) on some older video cards. In addition, the auto-saving system has been made more resilient to errors. Now it will not directly overwrite the old save. Instead, it writes into a temp file and will only replace the old save file when the writing is done.
