This may fix the text issue displayed in FF with custom display
settings.

 * Remove the background color.
 * Borders and icon darken when the input is in focus.
 * Adds the placeholder text back.

Added a readable class name to the search icon .icon-search and
regenerated the icomoon css file.

This is now a standalone module with no dependency on the Visual
Search library.

Small style adjustments to tags and the editor text area.

Fix spacing between icons and text inside buttons, improve spacing on annotation cards, add placeholder for annotation creation textarea, adjust padding on tags.

Convert SCSS variables into hyphen case

This makes all the variables consistent with each other and follows
CSS language conventions of lowercase with hyphens separating words.

Also updated form module to use our css color variables.

Be careful syncing $location.search and queries

Use ngCloak to hide UI that isn't ready

Pattern library first run

Does what it says on the tin.

The difference is that, while both get to intercept and handle the
response, only the transform can change the result that updates the
resource instance.

In this way, it's not necessary to copy the response data onto the
scope anymore because the object is updated properly in place rather
than being updated with the wrapped response containing the csrf
token and flash messages and other parasession data.

It is now provided via the data-form-validate-error-class attribute.

 * Validate on "change" rather than submit. This prevents errors
   appearing when the user tabs in/out of an input.
 * Keypress updating of errors in place errors to immediately indicate
   to the user when they have fixed an error.
