Altering how get_comments() works (Bug #1037531)

As I'm adding in some new options and I notice that Bug #1326425 will
also be adding options to get_comments so I thought it would be useful
to make a default opbject of variables that one can call and alter
with specific variables where needed rather than having to work out
where in the function call list things need to go as that list would
grow up to 10 options.

Adding ability to hide the edit/delete buttons (Bug #1037531)

Currently we are only trying to get the artefact comment list to show
as a 'read only' situation. Any editing/adding/deleting to be done on
the artefact/artefact.php page
