There are many occasions for Acedia where we might want to limit names
of objects to a certain predictable and manageable set and limitations
placed on config names seem to fit all of these cases.
That is why we rename `IsValidConfigName()` into a more
generic-sounding method name.
Additional change is limiting length of a "valid name" to 50 characters
at most, since Unreal Engine doesn't like loing config lines.
Several methods such as `Copy()`, `Remove()`, `ChangeFormatting()` and
several others have had similar errors related to how their input
parameters defined range when specified out-of-bounds.
This patch should fix them.
`Copy()` and `MutableCopy()` methods for `Text` incorrectly handled
negative arguments in some cases. They were fixed and appropriate tests
were added.
Now all objects only have to calculate their hash code once and it's
value will be stored for later `GetHashCode()` calls, since has code is
not suppoed to change during their lifetime anyway.
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.
