Use user strings file with event categories cog

[Laura7089]

Closes #52.

Not yet ready for release, posting here to gather comments about admin logs among other things.

wow you werent kidding, that was a lot of strings, thank you 😂
just a couple of typos to fix in there and then its ready to go!

[Laura7089]

Fixed all the above, there's a lot to keep track of with all the strings so mistakes slipped through!

I haven't added the admin logs yet, and intend to. Also, the logic for generating the loading text is a little complex and heavyweight for inserting into the toml file - can that be simplified with some clever format tricks to anyone's knowledge? If not, we can just split them up and build them in the code.

Edit: do we also want the command help messages to go into the file? They're user-facing messages and do match up with the error messages that are already in there...

[Laura7089]

There, admin messages added, with a missed message. The implementation isn't very pretty, but it will do for now, I hope.

In the future, we could consider grouping the related messages into submaps within the toml file and then pulling them in in cog constructors separately.

love this idea but user strings would have to be accessible at module import time - right now they're only accessible at cog instance time

Gotcha. I thought that might be the case, which is why I didn't replace them. That sucks - I'll open a tracking issue which we might get around to eventually.
