[MOD/WIP] Mark listing transactions as readonly

Browse source 
May want to sprinkle in "hinting" on the nature of operations done the
database, which could allow LMDB to deal with those far more efficiently
(for example, a read-only transaction can just be done as soon as the
JSON itself is parsed out, as we don't really need the former anymore!)
