UI: Fix poor handling of system tray pointers

Browse source 
The original pull request that added the system tray feature was riddled
with bad pointer usage.  Bare pointers that are never properly freed,
never contained within a QPointer or unique_ptr.

These have now been changed to use QPointer variables, and to always
check when the variables are valid before using.  The order of
destruction for QMenu that uses the actions has now been prioritized
first before the actions.
