Added ssh uri support

CHANGELOG.md

@@ -4,7 +4,6 @@ SHORT FUTURE IMPROVEMENTS (post v1.0)
 - Sync and delete propagation function merge (master and slave functions are the same, reduces code size and maintain effort)
 - Tree function merge (current and after tree functions are the same except for output filename and logging, reduces code size and maintain effort)
 - Tree functions execute piped commands (grep, awk) on master when launched on remote slave which can cause more bandwith usage
-- Fast sync mode should also work with remote systems
