Bug fixes
- item pictures in descriptive modal window are no longer clickable
- changed the modal message to box-sizing:border-box with padding rather
than just border which was making the content run off window.
Merge branch 'server-integration' of git@github.com:kizyahaha/MSB_website_design.git into server-integration
The content tabs in "My Profile" are now sized slightly more
intelligently.  Emphasis on slightly.
Added a global variables script to better track them.  Also added
Rickshaw graphing library, but haven't tested it yet.
A really super crappy implementation of a Rickshaw Graph.  Also changed
all functions to use a single global "user_ID" which is set upon login.
The global user_ID is reset to "" every time a new page is loaded, so
that's a bug, but none of this matters anyway because Billy has since
informed me that the back end will be dealing with the matter of user
ID's and the front end will simply request that information.
