Add component type to JavaClass dependencies

[codecholeric]

Now that #244 has been merged, we should add the component type of an array as a dependency to JavaClass.
For example

class Example {
    Dependency[] dependencies;
}

At the moment this would count Example to have a dependency on Dependency[], but it would not yet report a dependency on Dependency, even though that is obviously present as well.

Note that in reality this is not a huge issue, because if no other dependency on Dependency arises anywhere, it pretty much means that we only have the array, but never actually do anything with the elements of type Dependency, thus the dependency is a very lose one.

Nevertheless, now that we have easy access to the component type, it should be well possible to extend the dependencies to cover all component types of all array type depedencies.
