BASE constant setting: moved all to same base folder in 4dev/tests
check all other CONSTANT settings if they are already set and skip (used
only in Language default set)
Add missing phpunit check for array merge recursive
Various fixes in the logging class for more clear internal flags setting
and clearn up of complex type checks and debug validation checks.
Add basic debugger logging class phpunit checker (based on debug/print
and only very basic for echo)
Other minor fixes and updates (phpunit with inital dead code check)
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.
