Fabio Alessandrelli 711e96edc4 [MP] Make replication mode an enum + optimizations
REPLICATION_MODE_ALWAYS (sync) and REPLICATION_MODE_ON_CHANGE (watch)
are now mutually exclusive.

Prevent invalid NodePath from being added to the config.

Optimize the replication config loading by composing the lists on
demand.
