From now on, the cloud and dew have different code.

dew-dew channels, cloud-cloud channels, cloud-dew channel, are all separated. The next step is message design.

dew mode does not have to keep the whole chain. It works.
local mode works as if the dew mode has not been introduced. modes can be switched. Conveniently controlled through web and config file.

Dew sends accounts for cloud to verify. If they are not consistent, the cloud will send acounts to dew to replace.
