Show a tooltip in sequence view when hovering on a track's tab.

The tooltip can show the full name of the machine, and possibly other info. Currently names are cut off by the column width, so the tooltip would be clean.

If the machine name is != the plugin name, we could make the tooltip two lines and include both strings. Lets look at an example. If I use "FSM-Kick", we just show that. If I have renamed "FSM-Kick" to "beats", we would show: "beats\nFSM-Kick" or "beats - FSM-Kick". I tend to the latter form, as we could also use this in machine property windows. WDYT?

Yeah, I think the latter is better. What about "beats (FSM-Kick)". The parens don't clash with the dashes. In "beats - FSM-Kick" is seems like it could be confused for three pieces, beats, FSM, and Kick.

+1 for "beats (FSM-Kick)"
