My New's Year's gift to people:  Fix bug 95447 (Juk crashes without "track position" in the toolbar) in HEAD.

In addition I think I finally fixed the bug where re-arranging the track position entry in the toolbar would cause INSANE amounts of vertical space to be used.

Minor code formatting changes were also done, such as converting slideraction.cpp to be all one style of spacing.

I think this can be backported, I'll try to do so tonight.
