Minor clean up

• Biggest change was removal of a dependency with a low-priority security issue with one of it's dependencies.
• Added early work for sending payloads to issued commands - such as passing a security camera picture to desktop notifications.
• Added more granular machine learning time categories.
• Some minor machine learning cleanup (don't issue commands if target doesn't have a configurable number of events - useful for new devices).
• http and https servers now run in parallel by default - allowing web clients to have some added functionality (speech to text, desktop notifications) because they have ssl - and non-ssl for simple devices (such as SmartThings pinging back for event updates).
