Modal: Add prototype method for exceptions to enforceFocus

[JamesMGreene]

It seems that adding a new prototype method to Modal to deal with special exceptions for enforceFocus would be handy in avoiding situations like zeroclipboard/zeroclipboard#159.

jQuery UI has a similar extension point for their modal dialog, called _allowInteraction; see zeroclipboard/zeroclipboard#179.

i dont really understand what you want? seems like your proposed fix is legit? just override enforceFocus?

[JamesMGreene]

It's a legit fix, yeah. My concern is that fully overriding the method might lead to unexpected issues when a consumer upgrades their Bootstrap version, i.e. if that method changes in later versions to fix a bug or something. Obviously the consumer can just update their prototype override but that wouldn't even be necessary if there was a more granular extension point specifically just for allowing interaction exceptions.

If you think it's too much of an edge case, that's cool. However, the existence of that same extension point in jQuery UI makes me suspect it's come up more than a few times before.

hm… i think for now that your solution as is makes the most sense. It's not so much that it's a rare edge case, as that's how i really want people to be extending the plugins.
