qtgui: wip: adding control panel to time display.

- Handles setting autoscale, grid, x and y axis, and trigger modes. - Uses a new TimeControlPanel class to make it easy to insert and delete the control panel. - Toggle to turn on and off a new setting in the parameters box in GRC. - Pop-up menu and control panel should be sync'd with signals/slots. - Shows a dotted red cross-hair for the trigger when set to Auto or Normal.
