small patch for gdl2/EOControl/EOFetchSpecification.m

[Markus Hitter]

Hi,

when eliminationg my CVS conflicts, I came across 
-[EOFetchSpecification hints], where a NSDictionary is casted to a 
NSMutableDictionary. While this might work because ([NSDictionary 
class] == [NSMutableDictionary class]) in some implementations, it's 
not clean to do so, IMHO.

Attached a patch to do it more cleanly. I've left my comments in to let 
the committer see how it's done in the patched file.
