Title: New interplanetary transfer with porkchop plots

This adds a new interplanetary transfer maneuver that lets the user choose the departure date and the transfer duration on a porkchop plot. The transfer with the lowest deltaV is automatically selected, and you can zoom with the mouse wheel or by selecting a rectangle on the plot.
