Stable1.6.3
Updated the size of some VARCHAR database values which should solve issues on some hosts (ie. GMC) with outdated MySQL server versions
Added calls for CAMI hooks when adding users to xAdmin groups
NB: This update doesn't include everything that I was hoping it to due to recently having to go to A&E to get stitches in my finger, making it pretty difficult to do anything properly - expect some slightly slower support and less updates over the course of the next week or two until that's been sorted
