Normalize on a prefix for function parameters

* Normalize `callback` and `cb` to `aCb`

Not finished yet but shown for @Zren to see what I'm doing

Applies to #264
Use full naming for `aCallback`

Applies to #264 and https://github.com/Martii/OpenUserJS.org/commit/d7465a3d390d56693ce309aff80ee5bdbfe4df89#commitcomment-7004333

> You don't use short forms (cb = callback) with verbose varible name standards.

Not explicitly declared the STYLEGUIDE** but can be used to accomodate those who don't know what the short term of a callback is... been debating on making a minimum length too. e.g. not one letter identfiers with a potential prefix.
* At least 2 potential globals found
* At least 1 redundant/unreachable statement found

Applies to #262

Also some uncaught #255 because no code was executed before... but not doing all of these yet.
Controllers completed, I believe, and some testing on dev... still have libs to do.

* Changed "WARNING" on login page to "CAUTION"... a little too assertive... some users may want their email addy in there.
* Notated some STYLEGUIDE conformance needs
* Notated very short function name(s)
* At least one undefined identifier
Should be done with minimal breakage... testing phase now.
