[Drawkit] Fast Enumeration

[Rudy Richter]

I'm definitely in favor of leaving 10.4 support by the wayside.  Fast Enumeration and properties(and subsequently kvo notifications on property changes) are big on the list of benefits to going 10.5+.

Of course, that would make 10.5 the minimum OS that DK could be used with. Alternatively, it's possible to wrap enumeration in a macro that switches between old enumerators and fast enumeration depending on which SDK you are building with, but having experimented with it, it makes for less readable and rather ugly code.
