issue: shorten thold VRULE graph drilldown button title (#855)

* issue: shorten thold VRULE graph drilldown button title

The graph action menu now renders each drilldown button's title as a visible label, so 'Toggle Threshold VRULES %s' reads as an overlong menu entry. Shorten it to 'Toggle VRULES %s', add a unit test exercising thold_graph_button()'s VRULE branch (with the two missing request-var stubs it needs) so the changed line stays covered, and regenerate locales/po/cacti.pot.

* Update copyright notice in TholdGraphButtonTest.php

* Fix Last-Translator entry in cacti.pot

 ## ChangeLog
 
 --- develop ---
+* issue: Shorten the VRULE graph drilldown button title so it reads cleanly as a label in Cacti's graph action menu, using two complete 'Toggle Threshold VRULES On'/'Off' strings (keeping the Threshold reference) so the label stays grammatical across translations
 * issue: Log each template import error using its own message (#757)
 * bug: Element-qualify the `.thold-pill` CSS so it outranks the single-class theme rules (e.g. `.deviceUpFull` `width:14%`) that were clipping the pill to a fixed width; status pills now size to their label on the Device Status page and everywhere else
 * feature: Clicking an already-selected status pill now clears that filter (resets to All) instead of re-applying it, on the Thresholds, Device Status and Threshold Log sub-tabs
