ton of typo, grammar and punctuation fixes

I whipped up some code to strip out all the text nodes and concatenate them into a text block I could paste into an online spellchecker.  I chose the following one because it let me put in large blocks of text:

Worked off that list. Often when I found a line with a typo, there would be more there because it's likely it wasn't checked. Sometimes other typos gave me ideas to search the whole file for, like fixing all the "it's" that should be "its."  I probably corrected a few things in the comments to avoid having to determine context every time. I also fixed grammar (especially breaking up run-on sentences) when I saw it. I went through all the RS ship names and put them in single quotes since the text that's being spoken is already in double quotes. Otherwise, it just looks bad with double quotes nested in double quotes.  Ideally they would be italicized but whattyagonnado.

Wow well done!

It causes me physical pain to write things like "I don't believe that's cannon" but yeah, vanilla Mantis don't do that, it's a Slug thing as far as I can say. Some flavour texts suggest that the mantis speech is actual kicking sounds that are automatically translated into plain Fed-english by the auto translator).

No idea if even the single quotes will work correctly, FTL is kind of limited in it's Unicode use. Let's try.

So, I'm pretty inexperienced with this whole Github thing. What happens now? Should I take events.xml off? I'd actually like, cause I really don't like to edit things in the browser. Also, I really like that you submitted you changes immediately. I guess this is more efficient, cause this way people don't double correct the same stuff? Maybe everyone could make pull request and the other forks could also be merged for now, even if you haven't completed what you where doing? With event's.xml done, the bulk of the work is through, but I still like to go back to work offline on this soon. So maybe there should be a deadline at some point?
