Catches description using DC

This should make VuFind stores description of everything harvested using ojs.xsl.

Altough It looks like using nlm is better with OJS, I think it would be nice to improve this method too.

- Thanks to Ross Shanley-Roberts.

Conflicts:
	themes/bootstrap3/js/autocomplete.js

- avoids problems with e.g. combined search, permissions handling.

Smoother "must be logged" translation

- problems could be caused by trailing separators in MARC 505$t - e.g. for subfield $t content "abcde -- " this would result in ["abcde", " "] eventually displaying an empty row in TOC-tab

- Don't require non-empty catalog password (some ILS systems don't need a password).

Switched to trigger() for the selection event so that it can be bound to with the bind() function and the initialization function doesn't need to be modified.
Moved the autocomplete window to the form so that the bounding rect is not needed thus avoiding positioning problems e.g. when window is scrolled while suggestions are loading.
Align suggestions when window is resized.
Set the initial content with .html().
Use the greater of input width and form width for the maximum autocomplete list width instead of the arbitrary * 2 width.

Remove cat_password check in Shibboleth Auth Plugin

Disable xdebug in Travis build.

* remove cat_password check in Shibboleth Auth Plugin as not every ILS requiress a password (consistent requirements according to ILSAuthenticator)
