Adds the IQFeed to the Toolbox:
IQFeedDataQueueHandler implements IDataQueueHandler and
IHistoryProvider
Changes config.json to include IQFeed configuration.
At config.json "data-queue-handler" and "history-provider" should point to
newly created IQFeedDataQueueHandler to make the implementation work
Adds BasicTemplateForexAlgorithm.cs to test IQFeed implementation
