Added default Survey list templates for ProjectSurvey and GradingProjectSurvey.

Enable the ProjectSurvey and GradingProjectSurvey views in the core. Also add menu items to the program menu for easy access to these options. Reviewed by: Lennard de Rijk

Implemented taking ProjectSurveys. The user will first be served a list of all eligble StudentProjects for which the ProjectSurvey can be taken. After clicking on the list the key_name of the project is attached as a GET param and the code uses the normal take view with the hooks to let everything run smoothly. An extra access check method is required which checks if the Project mentioned in the GET param is a valid project for the current user. This check will run together with the isSurveyTakable checker.

Edit SurveyRecord model to not make use of different Survey property for each subclass. This does mean that a simple query needs to be constructed by hand whenever you want to query for every SurveyRecord for a specific Survey. However the naming is now the same over each SurveyRecord and it fits well into the rest of the design of Melange.

Made the CSV exporter for Survey not rely on the BackReferenceProperty in Survey.

Added getTakeProjectSurveyRedirect. This redirect is used when taking a ProjectSurvey.

Added the possibility to change the action of the form on the Survey take page.

Small style fix in Surveys helper.

Set required is True for StudentProject reference in ProjectSurveyRecord.

Removed obsolete if tag form take template.

Added hook methods to takeGet and takePost.

Fixed typo in title of Survey Take page.

Add a base implementation of takePost. Normal Surveys can now be taken, however comments are not stored yet.

Added getSurveyResponseFromPost method to Surveys Helper. This method will be used to read the POST dictionary from a request. And will transform it into the fields that need to be set in a SurveyRecord for the questions specified by the given Survey. A TODO has been added to handle the naming/handling of the comment fields.

Added updateOrCreateFromFields method to SurveyRecordLogic. The reading of the fields from the POST request will not happen in this Logic anymore.

Added base class logic for Expando based models.

Removed two obsolete/outdated methods in Survey Logic. The updateSurveyRecord can be found in the SurveyRecord logic.

Removed obsolote method call in Program View.

Clean up and other fixes for Survey modules. Reviewed by: Lennard de Rijk

Implemented the takeGet view for Surveys.

Fixed multiple typos in Survey tooltips strings.

Added skeleton for the take view and its template. Also fixed the sorting of imports of the Survey View.

Move getMenusForScope to the end of the View class. Adhering to our principle that we the methods we use for generating our menus can be usually found at the bottom of the View class.

Changed the Survey public view to give a preview of the Survey. Also changed the access rights for deleting a Survey because of the possible invalid references problem. Added two TODO's to the _public method. The first one involves enabling the SurveyForm to generate a form without passing along the Logic since it is only used to retrieve the Survey entity which we already have available. The second one involves a brief discussion about the getFields method's functionality and name.

Removed activate grade URL pattern from Survey View. The remaining methods will be ported over in a patch from Ajaksu.

Brown paper bag "without tea" morning typo fix in Survey View.

Style fix in Survey views helper.

Returned access checks in Survey View to the right state. This got bugged in James's commt.

Fixed too long line in Surveys helper.

Solved some merging problems and use the getRecordLogic where needed.
