Stuff required for Celery
Minor updates to .gitignore and the fabfile
Initial weight commit - can connect/disconnect a Withings account
Grab and display data. The grabbing is kind of ghetto right now...
Make DTs aware of TZs and stuff
Some niceities in weight for users and testers

- Holds on to your callback_url in the session
- Fetches data when you first associate your Withings account
    - The data table needs a spinner while data's not ready
- Deletes your Withings data when you disassociate the account
    - Might change this back, not sure how I feel about it.
      It's great for testing, and people who want to switch
      Withings users. But would anyone do the latter?
Rename some shiz
Fix default timezone
Subscription of Withings notifications
Added some weight chart goodness

Includes a sweet chart on the weight dashboard that shows data as soon as
some becomes available. This is mega-handy for when you first connect a
Withings account
some cleanup
Manual weight entry. Only allows you to use now() for the datetime for now
Add a header link for people who have access to weight tracking
Merge branch 'feature/weight' into develop. YEEEHAW!
