Alexander Nevenchannyy 06320d095a Move rally/objects -> rally/common/objects
There is no need to have objects directory on the top level.
They are quite rare changed and in most case one don’t
need to know about internal details of it to fulfill their
task. So hiding these directory under common/* makes perfect sense
