UI enhancement:
- On 'My Tasks' page and dashlet show links to initiator profile
- On 'My Workflows' page and dashlet show links to assignees profiles
Even more bits around related workflows compatibility with Alvex 1.2.x
'My Workflows' and 'My Tasks' - handle cases when initiator or assignee user is already deleted
Add 'Edit Task' button for workflow initiator and Alfresco admin (not only current assignee)
Merge remote-tracking branch 'origin/master'
