Release notes

This is a rather large update, it's advised you install this as a brand new style to test it out first. Instructions along with the XenBase change-log can be found here: https://pixelexit.com/threads/1-5-9-style-updates.4024/
As always back up your style prior to doing anything.

Note: This updates REQUIRES you to be on XenForo 1.5.9
