Support existing incompleted "reason" value for remove user and script

* One reserved phrase of "User removed" *(any casing)* for automatic content removal when a User is removed.
* Basic error checking... Moderators and above should be concise.
* Abandoning previous UI since portable devices would barely show the input box... plus a few things have changed since initial attempt.
* Leaving out the data list for now until it can be decided where to physically put and name it *(them?)* in the project tree... perhaps time for a user.js.

Applies to #261
