Pull request for Xtractpdf

Added Mike Wabiszewski as a developer.

Fixed issue with Monolog not logging to file and not outputting to FirePHP and Chrome Logger consoles.

Split logging into two files, in which normal operation writes to logs/xtractpdf.log and records error messages as the highest level of logging.  Development/Debug operation will write logs to logs/debug.log and will record all info and error messages.
