BugFix: color triggers get erased in 3.6.1 (Mudlet#1477)

In Mudlet@5ce683b

The writing of the (encoded) colour trigger data into the
(QLineEdit*) pItem->lineEdit_pattern in
(void) dlgTriggerEditor::slot_trigger_selected(QTreeWidget*) was removed if
the trigger item is a colour one - probably because in that type that
element is hidden from the user (as it was then also removed for the new
Prompt type trigger.
