Easier viewing and editing of moving items

[Benjamin Klum]

Sometimes it seems a bit difficult to edit or view currently playing clips because they move on the timeline.

re #58 Don't stow away playing clips when seeking in the timeline in order to avoid annoying disappearing items

re #58 When seeking to future, extend playing clips immediately not just gradually beat by beat

re #58 Prevent stowing away audio item (even if playing) as soon as user double clicks it. Rationale: The user's intent is probably editing the item. If not (maybe he just wants to have a quick look), it also doesn't hurt.
