Moved log4j and glitch config files from /config to /resources because
maven puts /resources files on classpath but not /config files.
Fixed slf4j dependency; mistakenly duplicated slf4j-logj12 instead of
pulling in slf4j-api. Added the assembly plugin for building jar with
dependencies (for CLI testing).
Created xml parsing of config file; Added more Configuration tests;
Added more logic to ExceptionManager.
