Portfolio API code in the assignment module expected that the current
user is the author of the submission. Therefore the "Export to
portfolio" button did not work when the submission was viewed by a
teacher (eg at the page with the list of all submissions in the Advanced
upload assignment).

This patch introduces a new callback argument 'submissionid' that holds
explicit ID of the submission the export deals with. With it available,
we do not need to expect the current user is the author of the
submission.

The patch also cleans some strings used for portfolio callback
exceptions.

When this code was used as a part of the grading screen, the default
PORTFOLIO_ADD_FULL_FORM widget led to nested form elements. This patch replaces
the form widget with a plain text link that can be embedded safely.

New PARAM_COMPONENT, PARAM_AREA and PARAM_PLUGIN + fixing of hopefully all current incorrect parameter types. This should help with diagnosing of incorrectly named 3rd party plugins too.

MDL-29189 mutlilang Reviewed the uses of course shortname and ensured things are being formatted consistently

For modules that still used the 'old' generic object return from _get_coursemodule_info instead of returning a cached_cm_info object, I changed them to use the new format as part of this. This made a few areas of code regarding onclick links slightly nicer.
