`RemoveItem()` method for `AssociativeArray()` is now able to deallocate
keys. `Empty()` method is now defined in a `Collectino` class and allows
users to recursively free nested collections, while deallocating their
keys.
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.
`AssociativeArray` by design does not manage keys, automatically
deallocating them, like it can with stored values. This patch adds a
parameter to `Empty()` method that allows it to deallocate all of the
used keys when deallocation all of the values.
As a side effect this patch also fixes a bug that broke
`AssociativeArray` after using `Empty()` method.
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.
