Changes

0.31 (Jan 2, 2014) - Agents now have an optional keep_events_for option that is propagated to created events' expires_at field, and they update their events' expires_at fields on change.
0.3 (Jan 1, 2014) - Remove symbolization of memory, options, and payloads; convert memory, options, and payloads to JSON from YAML. Migration will perform conversion and adjust tables to be UTF-8. Recommend making a DB backup before migrating.
0.2 (Nov 6, 2013) - PeakDetectorAgent now uses window_duration_in_days and min_peak_spacing_in_days. Additionally, peaks trigger when the time series rises over the standard deviation multiple, not after it starts to fall.
June 29, 2013 - Removed rails_admin because it was causing deployment issues. Better to have people install their favorite admin tool if they want one.
June, 2013 - A number of new agents have been contributed, including interfaces to Weibo, Twitter, and Twilio, as well as Agents for translation, sentiment analysis, and for posting and receiving webhooks.
March 24, 2013 (0.1) - Refactored loading of Agents for check and receive to use ids instead of full objects. This should fix the too-large delayed_job issues. Added system_timer and fastercsv to the Gemfile for the Ruby 1.8 platform.
March 18, 2013 - Added Wiki page about the Agent API.
March 17, 2013 - Switched to JSONPath for defining paths through JSON structures. The WebsiteAgent can now scrape and parse JSON.
