Began tracking frontend.

TODO db, form interface; more interactive charts.
Merge branch 'master' of https://github.com/QRAAT/QRAAT
New repo structure working on master.
Fixed query in __init__() of server/python/track.py.
build_qraat: build script similar to old build-rmg.  Must specify build target, i.e. build_qraat install node.
