CheckBox listeners

[michalrus]

For some reason a listener for CheckBox is named OnCheckedChangeListerer, while its method is onCheckedChanged—mind the last letter. 😞

Perhaps, an exception should be added to EventTweakMacros for this particular case.

@juanpedromoreno was working in this problem one year ago and he created a PR #58 for solving this issue. Finally, the PR wasn't included in the project

Maybe, you can help us to finish the issue if you think that it's important. Thanks

Not really that important to me, as adding a new Tweak to our code base is just a few lines. =) But it would be nice to have, nevertheless.
