Bugfix: owner of item (eg. conversation) can see the "edit button" on all comments in the item regardless of if she is able to edit that comment or not. The problem is the condition checks for the update permission on the item itself which shouldn't apply to the individual comments in the item.
Aligned comment reply/edit/delete buttons to the right
Added check for permission of siteOwner to edit/delete actions
reply button is now blue in idle state and has a extended right padding
