INTEGRATION: CWS macosxdnd (1.1.2); FILE ADDED

2008/01/30 06:02:18 obr 1.1.2.9: WaE: initialize tmp
2008/01/21 19:37:48 tra 1.1.2.8: Make code warning free, add support for FileList data type
2008/01/05 19:57:03 tra 1.1.2.7: Finally supporting NSDragOperationGeneric (command key pressed during D&D) which now hopefully satisfies all parties
2008/01/05 14:12:12 tra 1.1.2.6: More sophisticated default action determination
2008/01/04 20:15:37 tra 1.1.2.5: Some cleanup and removal of obsolete files
2008/01/03 21:11:15 tra 1.1.2.4: Improved drag action selection
2008/01/02 20:37:30 tra 1.1.2.3: #i79620# Cocoa based DnD implementation, not perfect yet but we wanna save what we have so far
2007/12/04 21:22:50 tra 1.1.2.2: Clipboard transition to Cocoa
2007/11/13 10:11:19 tra 1.1.2.1: #i79620# experimental Carbon based D&D implementation, no need to optimize - will be replaced by Cocoa version
