Tutors can now (once again) edit worksheets.
database: Created a new capability, 'edit_worksheets', which is set for tutors
    and above.
    The 'edit' capability for worksheets is now derived from the
    'edit_worksheets' capability in the offering, rather than 'edit'.
All checks to do with creating or editing worksheets (in general, not specific
ones) check 'edit_worksheets'. Checks specific to a worksheet still check the
'edit' capability, on the worksheet itself.
