Truncating tabs

Reg login validation

They do not need highlights, etc

fixes #268

*Actually* close #181 after realizing all the ways I wasn't
quite right, despite some light testing.

We *need* tests.

closes #181

Includes a change I need to merge upstream but missed my chance
for v1.2.6.

With this change all the bundled dependencies are included in their
unminified form to ease debugging and the asset pipeline, by default,
will use UglifyJS to minify them for production when debug mode is
turned off.

Additionally, the dependencies were upgraded where possible. The
current versions are as follows:

- AngularJS v1.0.4
- Annotator v1.2.6
- d3 v3.0.5
- easyXDM v2.4.17.1
- jQuery v1.8.3
- jQuery Mousewheel v3.0.6
- jwz 26aeec1
- underscore v1.4.3

The heatmap had to incur a slight change to accommodate the d3 upgrade.

Fixes #253

Remove all traces of the removed handlebars support

Added missing global switch for url replacer regexp

Reportedly this can choke some compass installations.

We can start to think of the bucket view as the base panel
and think about moving the viewer and the editor into the
sliding panels. The idea is that then the bucket view is behind
the editor as well as the detail view and the current viewer
becomes detail-only while the bucket is always underneath.

Also, the heatmap is back to adding itself to the element so that
it should be possible to move the heatmap out of the iframe
at some point soon, making it possible to absolute position it
with the full height of the page. This will also reduce postMessage
chatter when scrolling/updating.
