Automatic Spoiler Season (#2991)

* oracle now can be run in spoiler or normal mode

* tests for travis

* only run on relaunch

* spoilers in client (not oracle now) and tray icon shows when done

* spoiler status will be checked before downloading spoiler file

* only download if they care about spoilers

* reload db on spoiler download

* manual update button, code cleanup, and fix enabling sets when new

* cleanup, nullchecks, and fixes to spoiler

* reload DB even if not in spoiler season; necessary as we have a check elsewhere to prevent the reload if spoiler check happens

* Implement changes from 2991#issuecomment-356169374

* Change implicit nullptrs, alert on file deletion, minor changes

* make reload thread safe and minor changes from 2991#issuecomment-356450302

* Fix locking

* Disable update now button while process running
