Observing system

To allow for scripting of imaging flat fielding (e.g., taking a series sky flats in different filters) a new option was added which allows to change the instrument setup while the last of the requested number of flat field exposures (for a given filter) is taken.

The automatic focusing script was further optimised to setup the instrument and point the telescope at the same time, and necessary delays in the script have been tweaked to be as short as possible.
