Add configuration options for track's graphical and table views

[garrettjstevens]

User should be able to:

• Don't show table (separate from collapsing the table, just not show it altogether)
• Only show table (similar to above)
• Show table above graphical instead of below
• Split graphical and table displays into separate tracks

[garrettjstevens]

These options should be in the track menu. An example of how they might be added is:

(I just made up the action/state names for this example, they might need to be different)
