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.
Previously settings about side effects were scattered through different
relevant classes.
Now they will all be recorded in a single config object.
Additionally, log messages about both success and failure of introducing
these side effects.
This patch changes how `Feature`s configs work - they are now required
to use a separate config object (each `Feature` their own class, derived
from `FeatureConfig`) that is to be used as a `perconfigobject` storage.
`Feature`s themselves are not supposed to interact with their config
objects directly, instead using JSON-serializable type, which should
allow us a universal way to change `Feature`'s config variables during
execution.
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.
