Over-the-air deployment does not work with https (referrer lost)

When using https the referer is lost, therefore the OTA service does not work.
The new OTA service library provides a new template passing the referer as parameter via javascript to solve this issue.
Furthermore the used template and parameters can now be specified/overridden from outside the maven build. This way we can apply template changes without forcing people to switch to a new xcode-maven-plugin version.
