Add custom purchasable support

[timeverts]

Having had a brief look at your code, unless I'm mistaken, it doesn't appear as though custom purchasables can be included within product bundles.

Some examples of custom purchasables are:

• Digital products defined in Craft CMS's Digital Products plugin (https://plugins.craftcms.com/digital-products)
• Event tickets defined in Verbb's Event plugin (https://plugins.craftcms.com/events)

All custom purchasables extend the same craft\commerce\base\Purchasable class. The default Commerce product (which is actually a Variant) extends this class too, so it's really a custom purchasable itself.

If you want to see an example of supporting custom purchasables, take a look at the Promotions section in Commerce.

Thank you for your description, I think you are right. I will look into this and try to fix it.

@jerome2710, do you still have plans/capability to implement custom purchasable support?

@timeverts I have looked briefly into this. Given the fact that for product bundles you would like to give the user the ability to pick a variant, it is not possible to migrate to purchasables. A product is not a purchasable, but the variants underneath it are. Therefore I got stuck finding the correct relations.

If you have a suggestion, I'm happy to look into this again.
