 * This is a library for containing common used functions on Commons 
 *   BUT that could be also useful to other wikis
 *
 * Inclusion-scope: 
 *   "used by one or better more of the default or in one of the 5 most popular gadgets"
 *   "and is potentially useful for other tools on Commons"
 * Keep in mind: It's a library. Do not change any variable-state or the UI until a method is called.
 *
 * All things that are specific to Commons (as a media hoster) should go into [[MediaWiki:Gadget-libCommons.js]].
 * 
 * Coding convetion:
 * Do not self-refer inside a function using "this"; instead use "lc"
 * to allow reusing these functions in an altered scope
 *
 * Derived from [[MediaWiki:Gadgetprototype.js]]
 *
 * Invoke jsHint-validation on save.
