Kyle M Hall 003993d547 Bug 13473 - Plugins fail
When trying to execute or configure the plugin on 3.18 I got:

Template process failed: file error - doc-head-open.inc: not found at
/usr/share/koha/lib/C4/Templates.pm line 129.

Test Plan:
1) Install the Kitchen Sink plugin
2) Go to the configuration page of the plugin
3) Note the template processing error
4) Apply this patch
5) Refresh the page
6) Note the page now loads

=head2 themelanguage
my ($theme,$lang,\@themes) = themelanguage($htdocs,$tmpl,$interface,query);
This function returns the theme and language to be used for rendering the UI.
It also returns the list of themes that should be applied as a fallback. This is
used for the theme overlay feature (i.e. if a file doesn't exist on the requested
theme, fallback to the configured fallback).
Important: this function is used on the webinstaller too, so always consider
the use case where the DB is not populated already when rewriting/fixing.
