issue2550831: Make the classic template query.edit page work. R David Murray had a number of fixes. At least some of the fixes were already present in the devel and responsive templates. I touched up the html a bit and did what I hope aresome improvement for performance by shoving criteria into the filter rather than looping over all issues and filtering at the tal level. Also used R David's method to add a restore feature and work around an issue where a retired (deleted) query could still be in the active list. But because it was retired there was no way to manipulate it.
