Sprout from master 2015-11-19 20:18:57 UTC Frank Bergmann  <frank.bergmann@project-open.com> '- Fixed export_vars brace vs. brackets'
Cherrypick from master 2008-06-25 17:05:42 UTC Frank Bergmann  <frank.bergmann@project-open.com> '- added default project approval WF':
    sql/postgresql/workflow-project_approval_wf-create.sql

- replaces ad_export_vars with export_vars

  - Removed legacy OpenACS 4 header stuff
  - removed reference to ad_header for OpenACS 5.9 compatibility

  in order for compatibility with OpenACS 5.9

- Added workflow updates in order to eliminate
  "modify" as the first transition in a WF

  OpenACS 5.9 does not allow anymore single percentages
  without enclosing double quotes such as: width=100%
  Instead, we have to write now: width="100%".

  Removed workflow creation script, because it can only
  be defined in acs-workflow

  - Adding im_biz_object_member relationships:
    Now optionally accepts a current_user_id parameter.
    In this case it avoids checking the user session,
    avoiding possible errors

  added new im_trust_rel object type

  Fixed issue in im_biz_object_role_map which
  allows multiple duplicate entries

   Filter is to be interpreted as follows: Show all projects that fall into the period btw. start_date and end_date
-- Support use case: Customer can see past projects

  Alert mains are now sent to support@po

  Now dealing with the situation that im_biz_object_groups
  may not yet have installed

  Now checking if the dude was logged in already.
  In this case we just forward.

   im_gantt_assignment_timephases, im_gantt_assignments, etc.

  Fixed issue logging in manually

  Added parameter for auto-login to allow Unregistered User to login
  anonymously

  Added new procedure im_package_exists_p

  Re-activated the field "supervisor_id" / Project Sponsor
  for DynField definition.
