PEP8
Order jobs on ui by name
Add relations between models
datetime => _datetime
add status and run info to each job
Keep track of the current job status as well as the last job status

Useful for dashboards. Whenever tracking the last_run, reset if the status is "starting", as otherwise the information will be incorrect.
expose job status and run info to the job index
properly handle return codes for finished tasks and set the job status to succeeded
use minified css files
remove commented out code
change heading
Better index page

- Show the last status of a task
- Show the current running state of the task
- "Better" display of each task
- Use Roboto font from Google to display text
Fix header height to center h1s
Slightly better looking task definition

Still need to work on actual task running information, though the command information looks more spiffy
add missing utils.py
use moment.js to provide human-readable task running info
extract models into their own namespace

This will allow us to build separate backends - postgres for instance - without needing to redefine models
reference cronq modules with cronq prefix
Much nicer list view of events that occurred

- Group events by ID
- Show a running time for each job run
- Use human readable dates/times everywhere
- Show the appropriate status ball for each run
- Fix the button css to be a bit more flat and less bootstrappy

Still need to fix dates to convert from UTC to local time.
Remove old css
