Added support for printf logging

Also improved implementation to handle newline breaks within
a log message to prefix each line with the proper log level.
Merged print functions into write_msg

It is now possible to globally override the way lines are wrapped
or the prefixes attached or the output stream by subclassing or
overriding Log::Any::Adapter::Daemonproxy::write_msg

Also added more docuentation
