Standard use-case refactor

[javierggt]

Description

This is basically a refactoring of the current aperoll app to evaluate difficult star views.

The only major change in the UI is the addition of the ProsecoParams class. This is a small json editor where one can change most of the standard arguments to proseco.

The other changes are a restructuring of the code. The reason for this is that the code was very hard to understand. It was easier to write from scratch. Roughly, these changes are:

• new classes (ProsecoView, ProsecoData, ProsecoParams) replace the MainWindow and Parameters classes. Basically the same functionality in a better structure.
• move some functionality into a new ProsecoData class to deal with calls to proseco and sparkles, cache the results and export to file. This used to be in MainWindow.
• move some functionality from the old Parameters class into ProsecoParams
• move the rest of functionality from the old MainWindow and Parameters classes into the new ProsecoView class.

Doing this, I found cases where Qt signals would cause infinite recursion and fixed that. In other cases, the logic in the signals was not clear (a signal triggers a signal, which triggers another, so the dependence is not clear and makes the code hard to understand).

Another change is the addition of the AttitudeWidget (which could have been called QuaternionWidget) used to display a quaternion in different representations (and properly handle the signals when contents change).
