Epic. Version 0.4.1 is released which is configurable to fetch witnesses when requesting blocks.

Add a storage of watched scripts
Add a mechanism to process the filters and watched scripts
Add last synced checkpoint, channel to watch its updates
Make possible the kyoto node to start/stop, maintain the original peer list provided.
Add header cache for not to redownload them when applying.
Add wait_until_synced
Add tx broadcasting.
Add tests.
