Added tag v0-5-20090825 for changeset 776aae4d0499

Set new Melange version number to 0-5-20090825 in app.yaml.template.

Only create GradingRecords for succeful projects or failed projects with Surveys. This is done because it has no use to create new GradingRecords for already failed/invalid projects because the outcome of this one will have no changing effect on the status.

Set default taking access for GradingProjectSurvey to org. This will allow Mentors and Org Admins to take GradingProjectSurveys in case that an Org Admin has no Mentor roles.

Added org taking access to Surveys. This taking access means that everyone with an active role for any organization for a given program can take the Survey. This will allow one Survey to be taken by both Org Admins and Mentors.

Removed reference to GHOPTask and GHOPProgram. In addition changed required=True to False for information property.

Added GHOPStudent model which inherits from core Student model.

Changed GHOPComment model to inherit from base model. All the properties are specific to the GHOPComment model. The GHOPComment model is also made ID based. Changes changes property from StringProperty to StringListProperty.

Changed all status to start with Uppercase letters, made 3 properties required. Changed all the status to start with Uppercase letters because they are publicly visible. Also changed required=True to False for created_by, modified_by property to allow site admin to create and modify tasks. Also changed required=True to False for history to allow history not to be written until the task is published.

Reverting last 4 patches containing GHOP related views. As Lennard suggested all the model patches should come first followed by the logic and views patches, to make sure nothing committed breaks the existing code after thorough review.
