Refactor jail so that it's more self-descriptive and easier to understand by newcomers. Also, the test coverage has been improved.
Changes requiring status-react team actions:
* Replace Parse calls with new CreateAndInitCell and ExecuteJS bindings,
* Make sure web3.isConnected is ok as its response change to boolean value.
This PR refactors CLI API, removes obsolete commands and splits status code into smaller pieces:
* get rid of subcommands API (no ./status <command>)
* get rid of custom cli app package
* use stdlib flag package for handling command line flags
* move cross-compilation / mobile related code to lib/ package
* move wnode command into separate binary (cmd/node-status, name is subject to discuss)
* remove faucet command as obsolete
* update/add docs/READMES/wikis for new command line flags
It makes statusd code much simpler and smaller, separates concerns (lib, wnode and statusd are different things).
