Dioptas/Dioptas: Dioptas 0.4.1

New features:

• easier step selection for pressure, temperature in the phases widget and scaling and offset in the overlay widget, the steps are now selected by a spinbox which behaves more or less logarithmically (0.1, 1, 5, 10, 50, 100 etc.)
• the solid angle correction can now be switched off and on (please see the X-tab in the Integration View)

• Overlays overlays are now recovered in order when opening a previously saved project with more than 10 overlays
• cif and jcpds now als can handle trigonal symmetry (not only hexagonal)
• auto zoom for cakes works now correctly when browsing through several files
• entering numbers with a "," as a decimal separator works now correctly
• loading new files with automatic background subtraction enabled will now correctly keep the x limits constant
