Settings needs expansion

[uaktags]

The engine is missing alot of configuration opportunities and holds onto too many hardcoded aspects. Obviously a Settings class will have to be created and initialized directly after the DBEngine, because it needs access to get all the settings, then pass it onto every Module and Hook before they spin up.

The settings structure are kinda confusing. With groupings and actual settings value being in the same table.

How about having 2 tables:

setting_groups
settings

I would even argue for having configuration stored in plain PHP array files. Easier to debug.
