kohabug 1679 & 1680 Fixes date formatting in guided reports wizard

This patch corrects date formatting when defining dictionary definitions in the
guided reports wizard so that dates display according to syspref.

Date formating is also corrected in the report creation section of the guided
reports wizard.

It also corrects a javascript bug which caused some of the calander widgets not
to function properly.
