Just some fixups to a couple contrib directories I was trying out.

Browse Source 
. replace CREATE OR REPLACE AGGREGATE with a separate DROP and CREATE
. add DROP for all CREATE OPERATORs
. use IMMUTABLE and STRICT instead of WITH (isStrict)
. add IMMUTABLE and STRICT to int_array_aggregate's accumulator function
