Dioptas/Dioptas: Dioptas 0.5.2

New features:

• Added an azimuthal histogram for the cake view, please check the X-Tab in the integration view to change the integration bins in 2 theta direction
• Azimuthal range for 1d integration can now be set in the X-Tab ## Bug Fixes:
• fix calibration algorithm, which was currently failing most of the time for difficult geometries. It should now work correctly again as in 0.5.0
• fix display bug which was showing horizontal scroll bar in "calibration parameters" on some linux systems
• disable QT high dpi mode for Linux platforms, which was causing very tiny font sizes. It is working correctly without it
