Add 2 New Rules for Footnotes

[chrisgrieser]

see issue #39. Also ran npm run compile and npm run lint this time :)

I would have added #36 as well, but I do not know how to get the tabsize setting.

added further exceptions for the capitalize rule

I would have added #36 as well, but I do not know how to get the tabsize setting.

You can pass it in as an option, the user can set tabsize=2 in the settings. See the other rules for examples.

Okay just to be sure, I took the rules.ts from your repo, redid all the necessary steps again and commited once more. I have no idea what is/was happening with those tests that changed – I literally did not touch any of those things code sections that are supposedly changed.

Anyway, this here seems to work, all tests pass when compiling, moving footnotes to the bottom does not do anything when already at the bottom. Depending on what you think about the issue with the consecutive blank lines when moving footnotes, I think this should work (other than the tests that are changed for some weird reason.)

okay, modified the moving to bottom rule, now I think everything should be fine
