[Gmod-ajax] ViewerComponent.js cursor

[Mitch S. <li...@ar...>]

I just randomly came across this as I was working my way through reading
the code, and I happened to have dealt with this recently.

If the patch doesn't make it onto the list as an attachment, I'll try
again and paste it into the body of the message.

It would be nice if the cursor was the open hand (-moz-grab) while over
a draggable area and the closed hand (-moz-grabbing) while actually
dragging.  We could make dragDiv*Style.cursor="-moz-grab" in
VewerComponent.js to start with, but I imagine we'd want the cursor to
be something other than -moz-grab when it's over an actual feature, and
I can't think of how to do that off the top of my head.  Can you attach
styles to imagemap regions?

I haven't tested this in context, as I haven't gotten the full
ajax-gbrowse setup going on my machine yet, but I believe it's correct,
or at least close.
