Fix "Send by enter" on Windows

Apparently on windows `Qt.inputMethod.visible` is always true when an input method is installed. Also on windows even after removing the check enter is still consumed by the input method, not nheko.

Update nheko_de.ts: typo "Animiete"

Typo "Animiete"->"Animierte" and shorten the German phrase somewhat. Sigh, it is such a verbose language...

Control logging via command line or environment variable

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.

Restore compatibility with clang-format v11

on some linux distros) and because it didn't achieve its original
goal. See PR #1166 for discussion.
