newer version of the code

hi.

i’ve improved the code to report names of failed jobs, also made code more extensible if you want to fill other info to the job, such change can be accomplised with little effort.

also i renamed the plugin to check_backula_log, not to conflict with check_bacula that is in bacula contrib sources.
