Time has come to tidy that part of KMyMoney too. AFAIK there are 6 peoples more or less actively contributing to KMyMoney. That's less than reported, so this patch makes that clear for our users.

Inactive members were pushed behind active members and marked as inactive.
There were no Ralf Habacker - big contributor - on the list, so he is now.
Jack Ostroff has been pushed on top of the credits list, as he does awesome job with documentation and others on that list are inactive since long time.
Last but not least, now I'm on that list too :)

In placing names on authors list I took into account following statistics from git:
