Automatic analyze/optimization when packing

[Chordian]

trafficstars

Run the analyzer when packing, and if the tune can be optimized then either show a dialog box about it or perhaps just do it.

Alternatively, you could always ask first when the packing option is selected, e.g. "would you like to optimize the song first?"
