add collapsible SNI system tray, rename project to i3bar-mango

Tray: the bar acts as org.kde.StatusNotifierWatcher plus host (zbus),
rendering items on the right edge with icon/name; [tray] config toggles
expanded, show_icon, show_name, show_description. Clicks map to
Activate/SecondaryActivate/ContextMenu.

Rename: package, binary, config dir, layer-shell namespace and DBus
names are now i3bar-mango; mango is the default feature and the first
WM provider tried.

 Also, only the last "json block" is allowed to have a non zero (or absent) `separator_block_width`,
 all the other "json blocks" should explicitly set it to zero. If you think this definition is not
 the best one, feel free to open a new github issue.
