Incremented version to 2.4.14.
Added estimated burn time to delta-V display. Clicking on the delta-V column header will show an estimated burn time for the estimated delta-V. You will want to stop at the correct closest approach distance, and not necessarily when this reaches 0. When the throttle is off, uses max thrust. Otherwise, uses the current throttle setting for the current thrust.
Cleaned up the init sequence properly to get rid of any and all errors (such as the toolbar button disappearing). Hopefully.
