Cleanup, ML Improvements, Image Push Notifications

NOTE:

• If you are running AI version 20180525 or older, you will need to rename or remove your cache/db/processed.json file and restart SwitchBoard. Depending on the number of events you've stored, reprocessing events with the new time and date categories can take a while.

New features:

• Rework how images are captured so the binary of the images taken may be sent to other controllers.
• Add images to Pushover notifications when applicable (such as security cameras)
• Add app for Air Quality to trigger actions based on configured criteria (turn on air purifier if PM2.5 exceeds a limit, for example).
• Minor improvements to voice commands for blinds.
• Add app to remind me to take my dog out if it's been a while.
• Black Carbon values and reasonable safe levels populated for Air Quality.

ML Improvements:

• More granular time and date categories, allowing more accurate predictions (at the cost of more data needing to be collected and more memory consumed in storing it). What was simply 6 time categories and 2 day categories (for a total of 12 "buckets") is now 24 time categories and 7 day categories (for a total of 168 "buckets").

Cleanup:

• Change to catchErr to be consistent in var naming and avoid confusion.
• Documentation cleanup for machine learning values.
• Fix a rare bug for Nest if you don't have a designated "Home" name - default to "Main"
• Fix to light app that wasn't triggering "off" events accurately.

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).

Polish

Minor cleanup:

• Progress bar styling
• Cleaned up docs
• Small tweaks to existing apps (RSS Reader, Announce)

Feature changes:

• Paranoia filtering of all inputted values - even from reasonably trustworthy sources
• Global flag to set if you prefer Celsius for everything
• Add battery status to all possible devices
• Simple Chromecast device (see if it's on and pass in a YouTube ID - that's it)
• Air Quality device + app to alert if things get bad
• Twitter app allowing you to Tweet at your house to have it read aloud or delegate to Gerty to issue commands.
