Canvas support and various changes

[kometenstaub]

I’ve been working on supporting editors in canvas. I’ve also changed that the vimrc file is only read once. I also tried to implement nnoremap, inoremap and vnoremap, but I don’t know whether how I did it works. Here’s the diff:

I and some other users have been using it for some time now. This isn’t yet cleaned up and I probably won’t have the time to do so in quite a while. Furthermore, it doesn’t use the activeEditor property Obsidian provides, because that one doesn’t seem to work at the moment when I need to access it, so I keep track of the active editor myself.

This issue is meant to be a log.
