This reverts commit 234a4ca7.

Reason: No big deal Ryan, only there's a very strict policy in
docrails which allows public write access on the other hand.
CHANGELOGs can only be edited in master. If this is added I'll
make sure you get the credit for the patch.

Updated DOCS for engines and added a couple TODOs. Also, commented internal railties rake tasks description.
