If CMS is installed and a sub-module requires to be configured per CMS,
this is handeled by new 'CMSHook-(pre)conf.sh'
this has been added to Dev Docs
Updated postfix sub-module to use new CMSHook
Added 'itype' var for detection of install script type
Now also storeing 'Allways on modules' in installer as EnabledAons
Done because differences between distros is quite big,
and this was the beter solution then using alot of if statements
List of changes:
* Replaced service names php"$phpver"-fpm with $phpFPMService
* Replaced PHPver in package list with phpPkgName
* Replaced full php config path with $phpMainConf
* Replaced php pool path with $phpPoolDir
