Fix NOVA Core language files not loading

[ExE-Boss]

If a wrapper also defines a language file, then it will be ignored currently.

The Core and Wrapper language files should instead be merged, with the Wrapper language file contents following the Core language file contents, replacing Core lines where the Core and Wrapper language file key is equal.

To do list:

• Make the build script merge Core and Wrapper language files.

---

Ex. the following files should be merged like so:

Core some.lang:

core.foo=Core Foo
core.bar=Core Bar
core.baz=Core Baz

Wrapper some.lang:

(placement of core.bar is irrelevant)

wrapper.foo=Wrapper Foo
wrapper.bar=Wrapper Bar
wrapper.baz=Wrapper Baz
core.bar=Replaced Bar

Merged some.lang:

core.foo=Core Foo
core.bar=Replaced Bar
core.baz=Core Baz

wrapper.foo=Wrapper Foo
wrapper.bar=Wrapper Bar
wrapper.baz=Wrapper Baz
