fixes #521

The streamer api and client recognized the edit action as 'edit',
but the action name coming from api/store.py was 'update' so the whole edit action was broken.
Now using 'update' as a normalized name.

Reduced space between annotation cards.

Reduced space between annotation cards by 1/2. This is solves [issue 493](https://github.com/hypothesis/h/issues/493) and looks much nicer.

I have no idea what you all were trying to do, but if this field
isn't required just remove the required attribute!

- On deleted annotations, don't reveal that it was only a highlight.

Oops.

This reverts commit f62966937ca3d59b900d22bfc807486ecf0eeda8.

Will have to debug it first.

- Added sources and source maps for annotator

Modify standalone page so that highligh-only annotations look better 

Fix #504

Fix #511

The usage pattern for the authentication directive is to provide the
authentication service resource as the model. When this is done, the
template binding should take care of ensuring the model is correct,
eliminating the need to copy form values iteratively.

- Removed ng-inits
- Removed escaping from backend
- Removed de-escaping from frontend
- Removed no longer used tal tags

Fix #489 - singlequote character was not escaped when angularjs read the quote, text from the generated pt template

This reverts commit 94aa672a3afaf18fb6cc4c3d296fee5233dea36a.

Added "Claim a username" tab to make Auth/Login/Reg easier.

Dan wants us to use sans-serif fonts. I added a $sansFontFamily to the body element under //ELEMENT STYLES. It achieves the desired affect without screwing up anything as far as I noticed. Tilgovi, is this correct?
