Fixed issue #43: Duplicating blocks in survival (undo/redo not working in normal mode).

Browse Source 
Fixed QuickReplace in normal mode not placing any blocks.
Fixed blockstates sometimes changing on undo/redo.
Now clearing UndoRedo stacks on clientside when changing dimension or logging out.
Breaking mirror/array in survival is now possible again.
Breaking blocks in survival in any buildmode is now possible (previously only in normal mode unless instabreaking was enabled). Still with limited (vanilla) reach.
