Would be nice if FileAppender could create necessary dirs in path to the file
where necessary:

e.g. if I specify a filename, /var/logs/myapp/name.log
but some of the dirs don't exist, I just get an error.

Would be nice if it was possible to have log4j create the dirs if necessary.

I suppose this might not be wanted as a default setting, but there could be a
boolean createDirs property to turn this functionality on.

Wouldn't mind writing a patch for this if the idea is accepted.
