IdStory Identity Manager

Skipping of sending notification after new workflow task was created not worked if default property (in task configuration) was used.
I fixed this with using expression property instead default value.

<activiti:formProperty id="sendNotification" type="configuration" expression="false" writable="false"></activiti:formProperty>

I modified product workflow for change permissions. There are three places, where is notification send directly from workflow and universal create task notification shoud be skiped. I added this skip to these tasks.
