Plovim coverage

[42triangles]

Note: things that can be achieved in another way that's equivalent and needs the same amount of chords to be done, it will not be mapped. To give an example, s does the same as cl, right down to repeats (as in c2l does the same thing as 2s). And since cl can already be done in a chord, s does not need to get mapped.

Another note: everything below is the full listing of the txt files in /usr/share/nvim/runtime/doc/, not all of which actually contain bindings. I'll check them off once I've gone through them as normal though, though these will not get a commit attached since there will be none.

Yet another newer note: Removed all the usr_* files, since I don't think there are going to be any bindings that aren't also documented elsewhere.
