Add-ons Standard Library by Xon 1.22.3

Note; The 1.18.x branch will be the last branch to support XenForo 2.1.x

• Deprecate getContentPermissions function, as the 2nd string argument was not actually used, with a replacement function getPerContentPermissions added.
• Add \SV\StandardLib\Helper::isAddOnActive() helper function. Similar to \XF::isAddonActive(), except it understands version strings
• Shim template funciton is_addon_active code to understand version strings

• Add support for addon.json 'require'/'require-soft' to support addon version strings instead of the addon version_id.
  Uses version_compare under the hood after some very basic standardization.
  php version strings support dotted versions, '1.2.3' and also each part may also support special character strings:
  

  any string not found in this list < dev < alpha = a < beta = b < RC | Release Candidate = rc < # < patch level | pl = p.
