Fix failing tests for users w/o access to the ACCOUNT_PASSWORD env variable. Disable e2e public network tests in Travis pull requests. Exclude lib dir from unit tests.
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).
