1311223 - Stop using nsISupportsArray for window args

Status: RESOLVED FIXED

(Core :: XPCOM, defect)

Description

[Eric Rahm [:erahm]]

WindowWatcher allows for either nsIArray or nsISupports array to be passed in
for the arguments param. This converts all internal usage to nsIArray.

This is pretty straightforward. Basically:
 - "supports-array" => "array"
 - "nsISupportsArray" => "nsIMutableArray"
 - js code: 'AppendElement' => "appendElement"
 - (A|a)ppendElement gets extra "/*weak =*/ false" param

I really wonder if anybody ever passes /*weak*/=true to nsIMutableArray.appendElement.  r=me with changes below.

Might as well rename this to |args| to make it more idiomatic.

I *highly* doubt it.
