Message:

job_monarch/overview.php,
job_monarch/index.php:

• old code cleanup

job_monarch/index.php,
job_monarch/image.php,
job_monarch/jobstore.php

• rewrote session handling

job_monarch/image.php:

• supply DataGather? object to ClusterImage?

job_monarch/templates/header.tpl:

• add session to clusterimage
• (temp?) disabled pie chart

job_monarch/libtoga.php:

• wrote new SessionHandler? class to handle all sessions
• DataSource? now uses interactive port so can retrieve only relevant XML
• disable XML_OPTION_CASE_FOLDING to speed up xml parsing
• use jobmond poll interval to only reload XML when useful
• use strpos instead of strstr, should be faster xml parsing
• dont parse XML in ClusterImage? anymore, instead supply DataGather? object

job_monarch/conf.php:

• use interactive gmetad port now
