Merge branch 'missing-package-imports' into 'master'

Add TriggerRelease package back into master

This package was accidentally omitted due to a filter on package
names ending in "Release" (needed to filter out unnecessary auto-generated
packages from Tag Collector). It's now re-added at the current dev tag,
TriggerRelease-00-12-15.

See merge request !180
