Fix mappings for tags field

The tags field contained the wrong index_name: not_analyzed property
so because of this, this field was analyzed with the default analyzer
which split the search expression at hyphens.

Because we want to do case insensitive searching for this field,
the same analyzer is needed (instead of the intented not-analyzed)
as used for the user name.

Fixes #1251
Handle spaces in tags

The tag-it library is now configured to allow spaces.
However by default the window.open() function converts
the space characters in the query part of the uri to +
The streamsearch controller is now handling this conversion too.

Fix #1265
Remove _annotator_mapsrc directory

It's not reasonable to be shipping this here. We should be including
the source in the source map files or even including the source map
inline in the source map comment. The Annotator master branch does
this. For now, I'm putting the pressure on here. No source maps until
we get off this damn fork.
Fix tags search for page search

Had inconsistencies with tag and tags.
Unwanted console.log was also removed

Fixes #1267
Change default view to Document

Add a package.json for managing frontend dependencies

This allows us to install all but compass locally in the project rather
than relying on global executables.
Install frontend dependencies in bootstrap
Update webassets paths in configuration files

These now use project local dependencies rather than relying on them
being installed on the users PATH.
