LDEV-1352: The XML output for the tool data had xmlns="" for nearly all the tool entries. Now the namespace is set for each element and only the overall tool entry has the namespace specified.
LDEV-1352: The XML output had namespace entries (wrong ones) scattered throughout the output, so now nearly all properties have their correct namespace nominated. This isn't obvious when you use Firefox to view the XML - you need to look at the text file directly.
LDEV-1352: Added properties and the IMSLD conditions that use the properties, to selectively hide/show the branches. Updated the LAMS schema file and removed some activity attributes that don't need to be in the export.
LDEV-1717: scheduling beans are no longer singletons, so the server is trying to set up quartz schedule entries for two gates or two lessons at the same time then they won't interfere with each other.
LDEV-1511 use original constraint names for consistency, and so that we don't get multiple constraints on the same keys if the tables happen to already be innodb and have their constraints (i.e. script failure is ok in this case)
LDEV-1711: Grouping validation now checks that their is a branch in the current branching activity for each group, rather than just checking that exactly one branch exists for a group - if the same grouping is used for more than one branching activity then there will be one branch per branching activity.
