Better module api

[JLLeitschuh]

The changes to the README sum up the changes pretty well.

Guice Modules

Creating a module in Java requires quite a bit of extra boilerplate.

public class MyModule extends AbstractModule {
    @Override
    void configure() {
        bind(SomeService.class).to(SomeServiceImpl.class);
    }
}

class Main {
    public static void main(String... args) {
        final Injector injector = Guice.createInjector(new MyModule());
    }
}

This is the equivalent in Kotlin:

fun main(vararg args: String) {
    val myModule = module {
        bind(SomeService::class).to(SomeServiceImpl::class)
    }
    val injector = Guice.createInjector(myModule)
}

@SamCarlberg you want to take a look at this PR?

This is the big addition here that actually makes the API in the readme possible.

Okay, all of these Jacoco changes probably should have been in a different PR. But whatever.

❌ This is now double decorated. I should fix this.

[JLLeitschuh]

Okay, and I probably shouldn't have updated the version of gradle as a part of this PR either.

❌ This should be returning LinkedBindingBuilderScope.
