[Enhancement] Add the ability to put some icons in a popup menu similar to explorer's taskbar

[sneedmode]

Describe the bug
The tray does not appear on the taskbar

Reproduction
Everytime SCTT is open the tray does not appear

Expected behavior
I expected to see an arrow revealing the tray, like in the screenshots on the WinClassic Boards thread.

Screenshots

Environment:

• OS: (Win10 ver 1909)
• SCT Version (1.2.2)

[AEAEAEAE4343]

The screenshots on the WinClassic boards were not of SCTT, but rather of SCT's Open-Shell and StartIsBack++ configuration.

For SCTT to be able to detect all icons you need to disable hiding in Windows' settings (Personalisation -> Taskbar -> Select which icons appear on the taskbar -> Always show all icons in the notification area).

SCTT does not currently support hiding of icons. This will be implemented at some time in the future
