Add Documentation to Ecosystem

[bluddy]

Things to list: odoc, ocamldoc, odig, omod, ocp-index

Possibly add keybindings docs for merlin. At least for vim, the existing docs are a bit opaque. There is an issue for this, but it's over a year old.

(The doc file, merlin.txt, gives keybindings as e.g. <LocalLeader>t, and doesn't say what <LocalLeader> is or how to redefine it.)

The issue for improving docs at the Merlin repo has now been closed. I guess there will be no improvement in the docs at that end.

Also needed: a benchmarking section in ecosystem

URL for that issue?

[mars0i]

The link is above--second post. It's been reopened. Should be a small change to the doc file. I haven't gotten around to it yet. ocaml/merlin#578

I've only just realized quite how bad the merlin docs are. It's a serious problem.
