MDL-37030 Assignment: Fix error on download all submissions.

When group submissions and blind marking are enabled, an error is thrown
when a teacher trys to download all submissions in a zip. The fix is to
move the url rewriting from the plugin to the assign class so it is
done in a standard way by all modules. The rewriting is done to make images
in a text editor field resolve correctly.

MDL-31616 block editing: show in subcontexts does not work on category pages.

Thanks to Ian David Wild for pointing to the proper fix.
MDL-35793 question preview: config for the display options.

The settings control the display options used when a user
first previews a question in the question bank. Once a
user has previewed some questions, these are stored as user
preferences.

It may not seem worth making this configurable, but acutally
it is important when training new users to get them started
off using the right opitions.
