Better logging of message processing/processed

[bradrobertson]

Right now in my logs, I see messages like this:

08:37:02 mm.1      | I, [2015-09-16T08:37:02.415582 #73854]  INFO -- : Processing message for multiple-man-development.Contact.create.
08:37:07 mm.1      | I, [2015-09-16T08:37:07.768731 #73854]  INFO -- : Processing message for multiple-man-development.Company.update.
08:37:07 mm.1      | D, [2015-09-16T08:37:07.925792 #73854] DEBUG -- :    Successfully processed!
08:37:08 mm.1      | D, [2015-09-16T08:37:08.522758 #73854] DEBUG -- :    Successfully processed!

It's impossible to know from these logs which message was processed first. This would be useful information. It'd be great of MM could log the details of the message (eg "Successfully proccessed Contact.create", also maybe including the id)
