1.0rc6

After installing JPGraph 1.19 and re-opening bugtrackers home, jpgraph reported the php-notice about a already open session in the output : "JPGraph Error: General PHP error: A session was already started .. blabla"

This is due to the fact, that JPGraph comes with:
DEFINE("CATCH_PHPERRMSG",true);
in jpg-config.inc.

Change it to 'false' (as it should be like stated in the comment there for production sites!)  to ignore such errors.
