[UP-4139] Remove the reset password portlet and move that functionality ...

...into the login portlet.

[UP-4139] Rollback some whitespace only changes caused by IDE settings.
Loosely speaking, the "login" String here is an example of the Magic Number antipattern.  (I recognize it was merely updated not created here.)  I think it's a good idea to move hard-coded values like these into descriptive constants -- e.g. PORTLET_FNAME_FOR_PASSWORD_RESET.  But this item -- especially here -- is a minor issue.  It's a comment for future consideration.  I won't advocate holding up the merge over it.
