Subject: [PATCH] Logging class major change, Debug\Support update

old Debug\Logging is in Debug\LoggingLegacy and Debug\Logging extends
Logging\Logging

Logging\Logging is a new class with most of the functionality except
there is no more print/outout to screen, but we use the default log
levels (RFC5424)
The plan is to be a frontend between the old type class and
Monolog\Monolog

Updated all other classes to use new class interface
