Remove o7.com, lucameraga.it, hostelinsplit.com, and kotarac.net from the HSTS preload list.

o7.com: "our domain was incorrectly submited to the HSTS list" (broke www.smp-31.o7.com)
lucameraga.it: tried HSTS on CloudFlare, changed their mind
kotarac.net, hostelinsplit.com: "noticed an issue [with subdomains] in the latest dev build."
