Slack Share View

Little upgrade for share view of @Slack ios app that appears outside of it (f.e. when you press the share button in twitter or safari and then select slack option).

Kinda strange to force a user to select needed endpoint in an endless alphabetically sorted list, while there are things like.

I have an assumption that most of the shared things are send to stared channels/users/groups or recently opened dialogs. So why not show them in the first place?
