 /**
 @param	type	indicates whether tag is css, lastCss, js, or lastJs.  Optional prefix with "-" or "+" to temporarilty change the tagAddOrder
 @param args	additional args taken as files.  Each file in the passed parameters has the following special syntax:
 	-starts with http(s): no modding done
 	-starts with "/": no modding done
 	-starts with "inline:": file taken to be inline css or js.  Code is wrapped in tags before output.
 	-starts with none of the above: file put in path /instanceToken/type/file; ex: "/public/css/main.css"
 	-if array, consider first element the tag naming key and the second element the file; Used for ensuring only one tag item of a key, regardless of file, is included.
 @note	if you don't want to have some tag be unique (ie, you want to include the same js multiple times), don't use this function; instead, just set tag variable (like $bottomJs) directly
