Support emacs eldoc mode

[GoogleCodeExporter]

Add support for eldoc mode, which shows documentation and signature in the
echo area when you hover over a function or variable.

One source of info is the list of javascript built-in functions and
properties you're maintaining.

Another source of eldoc info could be jsdoc markup.

Marking as low priority, as this functionality is being handled by another 
project
I'm doing that should hopefully launch in 2010.

Steve,

What's the status on your other project that should provide eldoc support for 
js2-mode?

Thanks,

Nick

I would love to see this as well.  Just curious as to where would you get the 
documents?  On line?
