Data model object update

[pcmcpherson]

• manually updated data model docs: objects, events, fields.
• manually checked and updated sensor coverage for all data model objects, events, and fields, for newest versions of all sensors.
• updated index pages to point to the right stuff
• created .md template for Autoruns, and re-ran generate_sensors to get newest Autoruns page.
• condensed sensor references on the data model pages to just point to the newest version of each sensor; cleaner.
