Bug in DKEntity refresh method

[dblapps]

Just noticed this, in DKEntity.m, the refresh method is defined as:

• (BOOL)refresh { return [self refresh]; }

This just calls itself over and over until the app crashes. I think it should be:

• (BOOL)refresh { return [self refresh:nil]; }

or perhaps:

• (BOOL)refresh { NSError* error = nil; return [self refresh:&error]; }
