review official-allow_sameorg.json

Fixes https://github.com/RequestPolicyContinued/subscriptions/issues/10

Review process:
 * create a new firefox profile with only RequestPolicyContinued enabled
 * Default policy: deny, subscriptions disabled
 * visit each "origin" domain from the old subscription, one by one
 * on each site, check if a blocked domain causes obvious breakage
 * for each of these domains, check their owner info using WHOIS, common sense and other sources (Wikipedia, company info...)
 * if the destination domain owner matches the origin owner, allow requests for this origin->destination pair
 * also try to access destination domains directly to check for redirections to the origin domain and allow them if required
 * copy rules from ~/.mozilla/firefox/$profile/requestpolicy/policies/user.json over the old subscription
 * fix line breaks using regex, one rule per line (workaround for https://github.com/RequestPolicyContinued/requestpolicy/issues/339)
 * bump serial number

Differences with the previous subscription:
 * Some domains were dead and therefore not included
 * Some cross-site requests did not exist anymore and therefore removed from the subscription
 * A few websites seem to require signup to test them properly, not included.
 * A few websites prevent visits/usage from my location, therefore not included
 * A few websites force redirects to another domain based on my location, therefore not included

All origin domains from the previous list work as expected.
