A new parameter has been added to the display method, to define whether
the edit button should be displayed or not.
The H5P activity will display this button (if the user has the required
permissions). However, it won't be displayed when previewing H5P in the
content bank.
The $component = 'mod_h5pactivity' will be passed always to the H5P
player because it's required for being able to call these activities
from outside using embed code. The xAPI implementation checks whether
the information should be tracked or not.
