Fixed logging configuration. Now it is based on down-up discovery of project directory,
is not based on current working diretory and therefore should be more stable in different environments.
For example in previous implmeentation we had to put loggging.properties to user home directory in order
to get loggging when processor is running into Eclipse. Now this problem is solved. The fiile logging.properties
can be placed everywhere starting from classes directory and up to root. The first found file is used for
logging configuration.
