UI Jump list (AKA a contact list with jump to groups)

[SimonDarksideJ]

^{Issue created by @SimonDarksideJ as Bitbucket Issue #​17 on 2015.05.12 13:39.} Would be good to have a jump list control, that emulates the contact list functionality of most mobile devices.

Where the Scrollview contains a list of content broken up in to groups, with a group header added to the list. Tapping on a group would bring up the selection of groups, then selecting a group would then jump/navigate to the start of that group in the list.
