Add flags to configure use of cookies.

Browse Source 
Adds 2 new flags to the CMS:

- DisableCsrfSecurityToken
- DisableAuthenicatedFinishAction

DisableAuthenicatedFinishAction disables the session check on the finish completed action as this normally validates the user correctly posted a form. This page is normally just basic content so requiring a session cookie is sometimes a hassle.

DisableCsrfSecurityToken allows security token to not be added to the form. Normally acceptable as forms don't usually alter the state of the database.
