lex_utils: needs update

[sagotch]

I am pretty sure that https://github.com/geneweb/geneweb-contrib/blob/master/lex/lex_utils.ml#L148 need to be updated in order to make the script work.

  let repo_src = Filename.concat repo "src" in

We should be able to pass multiple directories to be looked up (recursively).

Yes, it should be "lib" indeed. I had corrected it, but somehow it came back!!
But I believe it is of no consequence as the recursive search for .ml files is done in repo rather than repo_src (this, by the way, scans plugins .ml files as well, but also the _default files which is redundant!!).
What needs to be done is reading templates into plugins/xx/assets, and this might be done with:

  let repo_tpl_plugins = Filename.concat repo "plugins" in
  let msg_tpl = List.append  (get_msg_tpl repo_tpl) (get_msg_tpl repo_tpl_plugins) in

Passing a list of repo to get_msg_tpl and get_msg_src might be a better solution!
We may also need to be a bit more explicit about which source file contains which message missing in the lexicon
although git grep might be deemed sufficient!!

Probably my fault then, I had troubles rebasing the PR.

And lexicon coming with plugins as well.

Could not get lex_utils.ml to work properly. (lack of line numbers in error messages does not help!!)
Restarted from old version and created lex_utils-2.ml which seems to work now (reads plugins lexicons).
Coding style can be improved!!

I need to work on this, missing location is definitively a problem.
