Small Typo and QoL-Update — Anamnesia - part 1: am i my body? Steam update #532328

Fixed a bunch of typos throughout the script that players have told me about. Since English isn't my first language, I'm blaming all of those on the proofreaders! :^) Aside from that I added two new buttons to the config menu. One allows you to activate a very limited backroll to read narration that you might have accidentally skipped. That totally goes against my artistic-vision(tm), aka being as annoying as possible about games as an art form, but I'd rather have people use that than complain about it. The other new button allows you to reset persistent progress, in this case which text you have already read (important for skipping on subsequent playthroughs) and which endings you have seen. This might especially be necessary if you first started the game right after release (before the update on the 23rd), since a bug caused all text to be marked as read right away. Well, only matters...
