Make filter expressions translatable

[krakan]

Description

Add some more strings for translation by moving them from javascript files to the corresponding HTML templates
Also make pressing enter in the filtering expression field less surprising by adding a new filter instead of submitting the search without the filter being created. If no new filter is being created fall back to the previous behavior of submitting the form.

Motivation and Context

All strings should be translatable to avoid annoying language mix ups. This PR fixes the remaining strings in query.js and search.js.

Screenshots (if appropriate):

The query page where Filtering by and Contains et al. were previously not translatable:
