Recognise "modules" on jsctags

[krusty]

Hi, great tool, I'm using jsctags with vim's TabBar, and it works fine, but It doesn't recognise this pattern as module: http://weblog.bocoup.com/organizing-your-backbone-js-application-with-modules/, maybe it's a syntax limitation, just wanted to make sure I'm not missing anything. Right now it lists all "methods" in the top level. I'm guessing it's because of the use of extend instead of new.
