Adds additional methods fo rconsole output, also changing how the old
one worked: now most methods do not output player's name in front of the
message, but `Say()` method was added if such behavior is needed.
Additionally fixed issue with `PlayerController` actor being stored
inside `ConsoleWriter` object before.
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.
