Theme : move edit button on left in find results table

Hi Seth

This pull request aims to solve the difference between objects in find results and other records. For objects, the modifier column is at left, for entities, places, occurrences... button was on the right side.
When using displays with many columns, it avoids to systematically have an horizontal scroll to find the button.
Meanwhile, this adds the i18n of the javascript sorting tooltips.

Bye,

Gautier
