AMQPUrlReceiver - receive urls and request headers via amqp in the format produced by https://github.com/internetarchive/umbra and add to frontier
spaces not tabs for indentation
license header
annotate CrawlURI with "receivedViaAMQP"
Merge branch 'master' into umbra
AMQPUrlReceiver - ack amqp messages, get rid of misguided thread starting infinite consumers
FetchHTTPRequest - include CrawlURI.getData().get("customHttpRequestHeaders"), if any, in http request
AMQPPublishProcessor - annotate urls sent to AMQP; set special fetch status; add default amqpUri; replace queueName setting with exchange and routingKey, which seem to be what are needed; avoid sending urls that were received from AMQP, and robots.txt urls; set content-type of amqp message to application/json, which umbra seems to need
syncronize start() and stop()
Merge pull request #38 from nlevitt/umbra
