Add basic tests for Android 2.3 on master, drop full support

[mgol]

jQuery 3.0.0 will include only basic support for Android 2.3, bigger non-critical workarounds like reliableMarginRight will be compat-only.

Those tests need to be written.

To not create further divergence between master & compat test files, I propose to create a separate android "module" with those basic tests. Thoughts?

I like the idea, but would rather see a name like "basic" or "minimal" so we're not tied to a given client—the same suite might apply to e.g. jsdom or PhantomJS.

Works for me. Good idea about jsdom & PhantomJS, btw, this might not be that hard to add once we have this.
