Remove Youtube importer #2014
Description
PYBOSSA has several integrations with third-party services like Youtube. These integrations were designed with Crowdcrafting in mind, but in the last years, almost all tasks have been created within PYBOSSA using CSV or JSON files via its API. Thus, that importer is no longer interesting, and we will focus more on improving CSV and JSON imports. It makes more sense to focus on an open format like CSV or JSON that can be created from any programming language from any external service (if it has an API).
