Test page and python script (!68) · Merge requests · nexedi / erp5

As requested this branch includes 'Python Script' and 'Test Page' to the migration. 3 commits:

First includes the new portal types and adds one test for each.
Second modifies guessExtensionOfDocument in order to be able to use content_type or reference even if the object is broken.
Third migrates all the files existing in generic ERP5 business templates. Migration created no other diff than those files.
