This update makes important changes to prepare sites for upgrade to XenForo v2.2

Important: before upgrading your forum to XF v2.2, make sure you are running v1.1.0 of this addon, then immediately after upgrading to XF v2.2, upgrade this addon to v2.0 - available here:

Changes in v1.1.0:

• rename apikey parameter in preparation for XF 2.2 upgrade and addon v2.x
• put in checks to ensure code isn't called if SparkPost isn't configured
• disable sparkpost if we're still running this version of the addon after upgrading to XF 2.2 to prevent breaking the forum
