Add a developer mode config section, where console debug logging, file debug logging, and reloading can be toggled
Add requests and psutil to requirements.txt

(also remove yql and tweepy from requirements.txt, so it will actually install the other dependencies)
Change "reloading" in developer config to "plugin_reloading" and "config_reloading". Also, now use plugin_reloading and config_reloading settings
