Allow multiple bundles to be specified

benabaird → closed merge request !15

The failing phpcs tests in MR16 are in files that were not touched by this work, so I've left them as-is to be resolved in a different issue.

Doesn't this lead to AmbiguousBundleClassException?

Very interesting, I was not aware that core considered these unique (it is documented).

Digging, the exception only is thrown when using ::create() from a bundle class.

There's some ambiguity in core on this, so closing this issue for BCA.

Thanks for looking, and for this very useful module!
