when modifying php.ini, use ; as the comment char not # because php emits horrid deprecation warnings otherwise
Merge branch 'owncloud' of github.com:jkaberg/mailinabox into owncloud
owncloud: set forcessl to be true to get the corret HSTS header (would be better if we could prevent ownCloud from sending one)
owncloud: automatically set it up with an administrator account that even the box owner doesn't have access to, because we do not want to have the user hit ownCloud's setup page on first visit
owncloud: support MOD_X_ACCEL_REDIRECT_ENABLED

This lets downloads from the file app work.
owncloud: fix regex in nginx config

/cloud/index.php/apps/files/ajax/scan.php would not be parsed right because of two .php's
remove owncloud step from README, no longer needed since 398b538e2b48c3764f67d75804af65bdb8b101d2
drop the owncloud mail app for now
owncloud will only let users access it from the PRIMARY_HOSTNAME (due to its trusted_domains option being set statically), so only include /cloud in the nginx configuration for PRIMARY_HOSTNAME
make setup/owncloud.sh idempotent: don't wreck user data on second run
ownCloud: code a way to add admins from our users table, but dont use it
ownCloud: do cron the same way we do the others
