Aliases were initially using `Actor`-base objects to manage themselves,
but that became a legacy approachin AcediaCore and they had to be
reimplemented without any `Actor`s (based on `Feature` instead),
allowing them mto be usable even when no `LevelCore` is provided.
I shamefully ended up doing another mega-commit, because a lot of things
needed to be redone at once and it was easier that way on me. No one
really consistently tracks what I'm doing with these commits anyway.
This adds a whole bunch of code to deal with proper clean up for Acedia,
so it doesn't crash on map change and also replaces old event/listener
system with new signals/slots one.
Now `LoggerAPI`, instead of simply loggin messages by itself, uses
logger objects (deriving from `Logger` class) to output log messages for
it (previous way of logging by `Log()` method is available by
`ConsoleLogger`).
Multiple loggers can be configured per each log level, which can be done
via config.
This is a giga commit, something that should not really be done with
git, but I messed up.
This commit brings a great amount of changes, most important is
reworking `TextAPI` and alsmost complete replacement of `string` with
`Text`/`MutableText`.
Another huge change is introduction of command system that allows to
define commands in a centralized manner, handles auto-parsing of
their parameters and auto generates help info.
Lastly, JSON data types were replaced with new
`DynamicArray`/`AssociativeArray` that are better designed and more
generic.
