Rename this repository to aap-core and the entire project to Audio Plugins for Android

[atsushieno]

It's been named as Android Audio Plugin Framework, but it will be problematic when it became really popular and causes possible Google TM issues. Can be done at any time, but I would probably do it when I create a dedicated organization.

No changes to module names, class names, etc. It's just about the branding.
