Changements
v 0.8.0
New Features:
Added a separate base conversion dialog to convert between different base numbering systems. It converts from/to decimal, hexadecimal, octal and binary bases.
Added a separate fraction conversion dialog to convert from decimal to fractional numbers. It provides a list of fractions in order of increasing accuracy.
A GUI font selection button was added to the Options dialog. This allows larger fonts to be used for high resolution displays.
A new GUI color setting dialog was added to the Options dialog. It allows a dark theme to be selected, or colors can be selected individually.

Updates:
Added the Beaufort wind speed unit.
R-value thermal resistance units were added.
The diopter/dioptre optical power unit was added.
Added the rydberg and hartree energy units.
Added the Planck constant as a unit.
Slightly adjusted the conversion value of the atomic mass unit (amu) and added the dalton synonym.
Slightly adjusted the conversion value of the astronomical (au) and the parsec units.
Add Swedish translation (thanks to Ake Engelbrektson).
Add Catalan translation (thanks to Pere Orga).
Update the libraries used to build the Windows binaries to Python 3.8 and Qt/PyQt 5.14.

Bug Fixes:
Fixed a problem with the ConvertAll window being positioned off the screen after major changes in resolution when using external monitors.
Clarified the labels for several power-of-10 data units (KB, MB, etc.) to show as "SI standard" rather than "IEC standard".
