Change operator canonicalizations.

Browse Source 
Streams are converted to their "official" names now.
Topics are not canonicalized at all.
All other operands continue to be lowercased.

Since we don't lowercase stream/topic at the parsing stage,
we have to modify the predicate function to do the lowercasing
of stream/topic to enable case-insensitive comparisons.  This
is slightly more expensive.  The server-side predicate
functions are already case-insensitive.
