[FEATURE] Bar relative context menus on systray

[ToxicMushroom]

Description of the requested feature

Example of a bar relative context menu.

Reasons:

• Looks nice and consistent
• The context menu then can't cover other systray items, allowing you to always access other systray items. Although I Just noticed that you can't directly switch to another item's context menu when you have one open so not sure how useful this is.

Proposed configuration syntax

:location ["bar" | "cursor"]
:spacing 8

Location would set the origin point for where to position the menu.
spacing would be applicable to :location "bar" to have it sticking to or spaced further from the bar
