This is a bit hacky, because we open a window to actually get a valid
activation token, but...

Can also be used to fix some corruption.

Since this causes crashes on some qml module updates.

Fixes #1383
Fixes #1132

Instead of completing the list of Linux, Windows and the BSDs (NetBSD and
DragonFly would still be missing), simply flip it to not-macOS to simplify

Log: maek closeAllNotification on all platform, move
closeAllNotification action to aboutToQuit

Nheko is very chatty in its log output, generating log noise (which
complicates diagnostics) and needless disk writes (which affect power
consumption and SSD life).  This patch introduces command line options
and environment variables to control log levels and output type.

The old --debug command line option still works, at least for now.
It is overridden by the new command line options when they are used.

Partially addresses #665.

fixes #903

fixes #842

This fixes date formatting as well as count based translations.

fixes #776
fixes #590
