Feature/register created by and updated by

This Pull Request adds:

• UserTrackable and UserTracker concerns to enable keeping track of who added a record and who edited it last;
• It integrates the above with litigations;
• It updates litigations admin pages with the created_by and updated_by;
• Updates litigations controller specs to handle this. Had to manually delete the current_user key, as it was persisting between specs and causing non existing users to be used in new specs. Wondering if this is the best way to do it. But I spent 2 hours banging my head against it, so I'll go with this for now.

Overall looks clean and great. You can try without request_store, take a look at my comment (disclaimer: I haven't used CurrentAttributes, seems like a new toy/double edge sword :P)

Forgot to say that is also worth to add updated_by, created_by to view page to be like updated_at, updated_by, created_at, created_by

[simaob]

you mean the show page? I added it to the index.

[simaob]

or you mean including the dates as well?

[tsubik]

Show page.

[tsubik]

I think it wasn't there.

[tsubik]

And we have annotate gem, so you can be annotate

[simaob]

Done! I've left the dates out of the index table for now, as I'm not sure if it isn't too much.

[tsubik]

Yeah, dates should not be on index page, I agree.
