Support for multiple domains per container

[dkarlovi]

If you're working with an app which supports multi-tenant setups, your HTTP container should respond to multiple hostnames (by the used hostname, application behaves differently).

For example:

• www.shop.com.loc -> English, international content
• www.shop.de.loc -> local German content

It would be cool if you could name multiple predefined hosts to use.

Oh, I see this should work already, but doesn't because of #32, closing.
