WIP: Consistent/Polished wording in Docs & Settings

[RyderForReal]

First of - thanks a lot for your work on this project. I recently started using it since I generally prefer to self-host things and it has been incredibly useful.

I figured that I'd make the titles and descriptions in the docs and settings more consistent and reword some cases of awkward phrasing. I'm still working on this PR, but was wondering if you had a preference for which kind of spelling to use (American English or British English). I'd just run a quick search & replace when I'm done with my work to make this consistent as well.

Thanks in advance.
