mondo combo bugfix

[woodslanding]

I fixed a bug with mondocombo that bugged me a lot:

If conductor#1 had item X selected, and I switched to conductor#2 which had item Y selected, mondoCombo wouldn't let me select item X for the new preset, as it fails the 'has changed' test.

So now, mondocombo takes an input from the combobox, which gets updated when the patch changes.

This means you could also display the current selection in the popup (but I didn't do that, because I don't really need that information.)

Hope it's useful!
