José Valim 50b6110106 Remove unused responsibilities and add a few load definitions to engines
Since plugins were removed, we can clean up a few methods in engines.
We also use this opportunity to move `load_console`, `load_tasks` and
`load_runner` to Rails::Engine. This means that, if someone wants to
improve script/rails for engines to support console or runner commands,
part of the work is already done.
