Make the undo and redo stacks non-static members of AssFile, making it theoretically possible to have multiple open AssFiles with working undo. Slightly improve tracking of whether the file is modified: saving, making a change, then undoing the change now results in the file being shown as unmodified as with most programs with undo. Add basic undo coalescing support. Originally committed to SVN as r4667.
