Remove unused code and classes.
Clean up code to remove all named constant from them and throw
deprecation alerts if used.
Add basic psalm setup in root folder and remove from www folder
If not created Logger class will be auto created in \DB\IO
Recommended to run a CoreLibs\Debug\Logging([...]); and use this class
for all ACL\Login, Admin\Backend, DB\IO, Output\Form\Generate calls.
Last parameter after DB CONFIG is the log parameter
Session create has been moved to a new Create\Session class from the
\Basic class and MUST be started before using ACL\Login. Currently
ACL\Login will fallback and start it if no session is yet started.
See the Readme.md file for which classes use _SESSION data
In future the _SESSION settings should be moved to some wrapper class
for this so we can unit test sessions
Only Output\Form\Generate class call has the new changed with the second
parameter no longer beeing the table width setting but the class
setting.
But as this is a semi retired class and only used for edit_base this is
not 100% breaking.
All other classes can be used as is and have internal fallback to run as
before.
Deprecation messages will be added later.
