[Time Conductor] Move History button from popup to Time Conductor body

Is your feature request related to a problem? Please describe.
The Time Conductor (TC) includes a History button which lets the user select from a menu of previously set timeframes in both real-time and fixed time modes. Currently that button resides in the settings popup. This was not the original design, and requires the user to click a number of times to both access and apply the settings from the menu.

Describe the solution you'd like

• The button should be moved into the TC body to the right of the end bounds input(s) in both real-time and fixed modes. See screen mockups below.
• The currently present gear icon at the right of the bar, which is non-functional, should be removed.
• Clicking the History button directly should invoke its menu, and selecting from the menu immediately applies those settings and dismisses the menu. Outside clicks would dismiss the menu as that gesture does elsewhere in the app.
• These changes should be made in both the main TC and independent TC interfaces.
