Minimizing KStars dependency on KDE's KIO framework. This should help facilitate migration of KStars to other platforms especially for embedded devices where KIO is not available. KIO is still used in several places that are quite unlikely to remain in the desktop
version of KStars such as the calculator.

Please test this huge change as it introduce regressions especially on the observation manager and any task that requires any download of any sort.
