Thank you, q234rty, for the help with debugging this.

Turns out that setting the desktop env isn't enough we also need to 
manually ensure kwalletd is started. As we can't tell steam to run 
multiple commands, people will need a small wrapper script that 
does this.

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.
