> "" (imp).plist
Made the default include «current filename without extension».h

> U   branches/WIP/Bundles/Objective-C.tmbundle/Snippets/020 Class  
> (objc).plist
Made the default class «current filename without extension»

> U   branches/WIP/Bundles/Objective-C.tmbundle/Snippets/#import <>  
> (Imp).plist
Changed the default to #import <Cocoa/Cocoa.h>
