Currently, depending on the wikiproject, the function used for getting URL parameters is called either "getURLParamValue" ([[MediaWiki:Common.js]]) or "getParamValue" ([[commons:MediaWiki:Common.js]])
It would be preferable to have only one function for this, available by default from some MediaWiki file. The function could be available through a name of the form "mw.get...()"
