Added an @array "options" parameter to user_get_user_navigation_info(),
for passing in avatarsize, and possibly other options in future.
Also removed an errant parameter in the /lib/outputrenderers.php
user_get_user_navigation_info() call, as there was no corresponding
parameter in the function definition.

On some pages full user data is not stored before user_created/
user_updated event is triggred. So giving option to trigger that
manually, so it can be triggred after all data is saved
