Activitybar Separator

add up to 5 seperators to your activity bar, so you can easily separate/categories your views shortcuts.

# How To

we use viewsContainers to add the seprators to the activity-bar list which also means that we'll have to create an empty view for that item.

it doesn't affect the usage in anything, except when u press on any of the seperator items, you will open an empty view.
