The Logger/MessageLevel gets "success" as level 110 to something a bit
heigher than "ok" which is the general "OK" for anything ending without
an error. The "success" is currently only used in file uploads with the
java script ajax file uploader
Fix any "type $var = null" with correctly "?type $var = null" for PHP 8.4 (phphan)
Fix preg match no return catches for DB IO compare version and for language
look up.
So we can have different stylesheets for the levels like in the error
messages.
Output changes to ...[$target] = ['info' ..., 'level'] and on return
this is converted into an array for each entry so it can be handled
like the error msg return string
if log level is debug, automatically log the error messages.
We still skip warn and info levels from logging.
The rest is based on the logging level (notice eg only gets logged if
log level is at least notice)
