Get rid of the inAdderClick logic

Instead of setting/resetting the inAdderClick flag,
we can just override mouseUp on the adder click,
and stop propagating.

Update Annotator PDF plugin to support latest PDF.js in FF34

Remove console.log statements from within the app

Log statements do not belong in production code.

Don't swallow exceptions when scanning the document

According to @csillag, there are no good (i.e. non-exceptional) reasons
why `this._scan()` should throw an error. As such, should not be
catching and swallowing the error, as this will make it much less likely
that we receive bug reports about brokenness in dom-text-mapper.

Inspired by conversation in #1596.

Add link to terms of service on create account form.

This update brings support for PDF.js v1.0.712, and thus FF32.
Closes #1592.

[WIP] add support for packaging with PDF.js extension - try 4

 * Don't load the Document plugin for PDF files; Annotator's PDF plugin
   provides the fuctionality (uri+metadata extraction) in these cases.
   Use async metadata extraction for PDF

 * Updated PDF plugin to fcdf1eac (pdf-update branch)

Close #1586

Only add the public principal to the annotation

We now wait until the annotation has been created and apply the
principal to the read array rather than overwriting the entire object.

Make replies public by default 

This fixes the annoying issue with replies defaulting to private
all the time.

Is bad. And IE doesn't like "initial".

Now allows permissions rules to be provided in the
beforeAnnotationCreated hook.

Add 404 page

Since the change to the stateless identity API we have not been
finishing the initialization when the user is not logged in.

Restore clearfix on form fields

This reverts the change in 8955140efeab69d0a88e3df69b59e21f6d394044.

Separate login errors for username and password

Prevent tag input field from changing height

Validate that email exists on forgot_password

Add a new simpler grid system.

This fixes an issue with floated columns failing to clear each other
when of different heights. We now use a flexbox implementation taken
from the Pure CSS grid system which fixes the whitespace inconsistencies
in Safari.

Improve math support for matrices, inline content and list item and block quotes containing math.
