fix: add tcp port support (#38)

* Support multiaddrs with tcp/port/\{ws, wss\}. Fixes #37

* making linter happy

* docs: use multiaddrs with tcp port

* enforcing travis detection on travis env

* reverting previous commit

* tests: deactivating this test that fails because travis detection is failing because env vars are not being propagated into the browser

* linter happy
