squashed bugs re: ping count and last ping time
fix logic for resetting sidekiq queue
Nag#declare_done repopulates sidekiq
Nag.create_nag generates next_ping_time for nags made via text
put explanation on home page
update pages to be clearer
fix Nag.populate_sidekiq to not run if there are no active nags
install foundation
Update home page appearance, change generate_next_ping algorithm to make nags further apart
