[SVN] r10582

[Allan Odgaard]

Refactoring:
• introduce filterString accessor (which appands mutablePrefix to staticPrefix and returns that) and use it where appropriate
• use ?: instead of “a = …; if(!a) a = …;” when accessing ‘match’ key and falling back to ‘display’ of the candidate items
• remove arrow up/down handling since the table view should no longer receive these as key events
