Strict error reporting fixes (php5.4) and comments

Strict error reporting shows a lot of mismatches between parent callable methods
  callbacks and overwrites, parameters need to match

Also added docblocks and tried to fix formatting to adhere to CakePHP conventions
  no functionality changes here, but general cleanup...

(more to go, these are just what showed up)
