The license text was removed from the Advanced section of the settings
menu and placed into its own About section. Users can now also discover
the commit hash of the build they are running through the UI, instead of
having to comb through logs, or use git.
* Add relevant section for Debian >=10 / Ubuntu >=15.04, thanks to antiatom for
supplying list of ffmpeg packages
* Add ffmpeg to Arch install instructions
* Add mention of supported PKGBUILDs for Arch
* other small visual and spelling fixes
After loading SettingsSerializer would keep the last group/array as current, so setting new values before the next beginGroup/beginWriteArray would be added to this group/array wrongly
This has zero inpact on qTox since we don't load before saving
Qt doesn't get mouse move events after a right click, so right clicking on a GenericChatroomWidget would get it stuck in the highlighed style until hovered in and out again
We now explicitely interpret a right click as the mouse going out and fix the style accordingly
Since the stylesheet has precedence over a QPalette, there wasn't a clean way to handle that with a stylesheet, so we now use a QPalette directly
We now use a binary serialized format to save space and allow clean encryption of the user settings.
All the settings can (and should) be edited from the GUI so there is no loss of functionnality.
It can still read the old .ini format, and will seamlessly upgrade to the new format.
Fixes#1810
