Nheko is very chatty in its log output, generating log noise (which
complicates diagnostics) and needless disk writes (which affect power

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.
