Test 2 "Tooltips" set up.

Features Needed:
- Tooltips
  + Room number
  + Occupants
- Rollover effect
Tooltip implemented, untested
Set up bower package manager
Added simple Ruby script for a devserver

The server script takes the directory it is run from as the root
directory and server files on port 8088.
Refactored code for multi-floor data files

The new code is more in the spirit of d3js because images are
loaded based on the data instead of manually loaded.

The code has also been commented for clarity.
Tooltips refactored to work
Merge branch 'testing'

The testing branch contained refactoring to better enable multiple
floors and includes tooltips for the rooms.  In addition, config
for the `bower` package manager is new to the master branch.

Conflicts:
	js/housing.js - kept comments from master, code from testing
	tests/readjson.html - dropped old master code
