Add a new test file at the end that verifies cleanup

Verify that there are no url hashes left when the suite ends. This should help catch cases where a test clicks on an anchor tag and causes a navigate vs running a halt() on the click event.
    Zip file handling in sandbox mode.
Merge pull request #115 from frankban/sandbox-zip

Zip file handling in sandbox mode.

This is another incremental step in the
implementation of the local charms upload
functionality in sandbox mode.

This branch introduces the zip.js library
as a GUI dependency. While in the process
of integrating it, I also added the steps
I followed in the HACKING file. 
In reviewing this branch, you can safely ignore
the following files: zip.js, inflate.js and
deflate.js. 

Note that the zip-utils.js file is instead 
a new internal module I added to collect
helper functions for working with zip
archives.

This does not add so much functionality 
except for the integration.

QA:
1) make debug;
2) Open the GUI and the js console.
3) Drag a zip containing a charm in the zip root,
   and click "upload":
  - you should see the "charm upload in sandbox 
    mode is not yet implemented" notification;
  - in the js console, you should also see a list
    of the three files we are interested in, included
    in the zip.
4) Do again setp 3 but this time with a zip
   including the charm in a nested directory
   (e.g. a zip like this is in 
   https://github.com/hatched/ghost-charm).
5) Now drag a zip not including a charm:
   you should see an error notification similar to
   "unable to find the charm configuration file".

Done, thank you!

No QA only code review for now.
Create the infrastructure to determine when a user is dragging a file over
the browser so that the application can react accordingly.
