Convert %{echo:...}, %{warn:...} and %{error:...} to work via lookup table 

Handle log level determination inside doOutput() to make the interface
match with the others and as a bonus, make expandMacros() that little
bit smaller again. Empty argument needs to be handled differently
but shouldn't affect functionality.
