Title: Settings for easurements ellipsoid moved

Moving the settings for measurements ellipsoid from Options menu to Project menu, and storing them in project settings instead.

Why?

The measurements are not only used for viewing anymore, but also for calculating area and length in field calculator. As some
tickets have been submitted that pointed out that different lengths of the same object in field calculator and
the GUI is confusing, work was done to rectify this. In the process valid concerns were made regarding that the same project with
the same data would yield different calculated - and stored - results in field calculator, if the local settings for measurements were not identical.

Moving the settings to Project will make it possible to always come to the same result regardless of installation. It is as a bonus also easier to
set different ellipsoid depending on project, e.g. one project is depicting Mars and another Earth.

This will fix issues 3296 and 4252.
