Ignore compiled js in a useful way

[nickvergessen]

See https://www.transifex.com/nextcloud/nextcloud/translate/#es/notifications/150036672

Would need something similar to:
ea5ff0b

But I guess instead of creating a huge list in our docker-ci, it would make sense to allow the apps to specify the list themselves.

Would it be ok to extend the list until another solution is ready?

[nickvergessen]

@rakekniven yeah do it for now ;)
PR welcome 🙈

@nickvergessen I commited directly by accident. See f50a12b
Sorry for not providing PR.

I triggered and update of the images. Let's see if it builds correctly.

Fixed by 27466b7

One could now place a .l10nignore file inside the root of an app and all entries that do not start with a # will be added to the ignore list.

I will add some documentation for this.
