added description bar to the top of all pages
Fixed UI issues on markets page
Fixed text underline in Firefox
Added superusers + superuser view

This adds the ability for superusers to sign into our system and manage
vendors.

I have deleted all server-side scripts for activating/adding Vendors
since it made little sense to leave these around. Instead, we have a
script called addSuperUser.py which will make a registered user (either
a customer or a vendor… it doesn’t matter which) into a superuser based
on their id.
Added address to manage serializer.

Now the address for vendors will be displayed on the management page.
