Use log service for console messages (#221)

* Use logService for console messages

* Implement a base ConsoleLog service

Use this class as a default for other services that would like to output
to console. This service is overriden in CLI and Desktop to use CLI's
consoleLogService and electronLogService, respectively.

* Use browser-process-hrtime for timing

* test LogService implementations

* Ignore default import of hrtime

* Clean up imports. Require ConsoleLog injection
