ocp-grep: add options to search in strings within ocaml files
Added a print command to print info following a user format
Save original path info, to retrieve the origin after a module open
Move project-root finding heuristic to IndexMisc
ocp-grep: lookup project root by default, ignore hidden dirs
emacs mode: fix escaping of ocp-index call parameters
We need to check that this still works for #26: @dbuenzli, can you please confirm ?
emacs mode: add ocp-index-grep to find uses of the ident under point in the whole project
Bound to `C-c /` by default
emacs mode: customise ocp-grep path
emacs mode: option to show the doc bubble on completion
(useful even on already complete idents !)
