Add filtering to the ISO Tracker Defects Summary
The QATracker is the tool that the Ubuntu QA team uses to track the results of manual testing. This tasks assumes you have already setup a development environment and are ready to code! Do the 'Setup a development environment for the QATracker' task first if you've haven't yet completed it.
Your tasks are to add the ability to filter the Defects summary, http://iso.qa.ubuntu.com/qatracker/reports/defects , for the Iso tracker by date and to replace the current Committed (Com), Subscribed (Sub) and Duplicate columns with one column representing Bug Heat.
The full bug report for this can be seen at https://bugs.launchpad.net/ubuntu-qa-website/+bug/1366579
To complete this task, you'll need to propose a merge with the changes and have them reviewed and accepted.
