moduleapi: Add 'peek' to :may() and new :could() helper to suppress logging The current method logs scary "access denied" messages on failure - this is generally very useful when debugging access control stuff, but in some cases the call is simply a check to see if someone *could* perform an action, even if they haven't requested it yet. One example is determining whether to show the user as an admin in disco. The 'peek' parameter, if true, will suppress such logging. The :could() method is just a simple helper that can make the calling code a bit more readable (suggested by Zash).
