Added “Obsidian footnotes¹” plugin, bound it to <C-R>, adds numbered footnotes. Emulates my old vim footnote macro, except that footnotes are numbered and therefore automatic.

Ideally (for the master page, hypotetical merging of markdown files) I’d allow for non-automatic ones as I had in vim (I type whatever, press the footnote shorcut, creates a footnote with index whatever) and this would be a nice case for a simple obsidian template but I won’t be doing it in the near term.
