commented out window.location.hash="";

I'm no expect at jQuery (total n00b in fact), but it would seem
that the issue described here: https://github.com/spsaucier/App-Folders/issues/3
is being caused by the `window.location.hash="";` line.

Upon removing it, the script stopped jumping back to the top.
Merge pull request #5 from LimeBlast/patch-1

commented out window.location.hash="";
Added support for InstaSwitch

Using new option instaSwitch (default false), you can set App-Folders to
switch to another folder on click rather than closing the open one
first.
Misc. other improvements as well. HT Thomas Park
