FARSIDE_CRON allows turning on/off the scheduled instance availability
check that occurs every 5 minutes by setting the variable to 1 (on) or 0
(off). The default behavior is "on".
Although the current list of queries is only 2 elements ("time" and
"weather"), this allows searches for Whoogle and Searx to be slightly
more random, and potentially avoid any issues with their parent engine
rate limiting them.
Rather than requiring a traditional crontab install, the app now
leverages quantum-core (link below) to schedule the instance update/sync
task every 5 minutes. Some updates as a result:
- The new job is scheduled at runtime in server.ex.
- The update.exs script was refactored to be compiled along with the
rest of the app as instances.ex.
- Scheduler and Server modules were added for creating and executing
the new update task
- All shell scripts were removed, as they are no longer needed
