Fix time based settings and return old proto version support.

Correct time settings
Return support connect from old protocol versions for old solutions from BTC ( not return support old node before fork )
Fix setting test network.
Fix testnetwork ports.
pump version.

I recommend update to this version if you need old node for out dated software.

Otherwise upgrade to the latest version based on 24.0.1
