Add support for VMs without private/public networking

[radeksimko]

When VM does not have any explicit private or public networking defined in Vagrantfile, all services on any ports are obviously available on 127.0.0.1 by default, which is also IP used when SSH'ing to that VM.

Users might not want to setup any public/private IPs just because they want set up hostnames.

In general - is there any meaningful reason to not support this?

+1, for me also public didn't work (as stated in docs, you need static private IP). I saw that line after browsing this issue, so maybe it would be nice idea to at least bold this part in docs?

Could it be conditional i.e. disable-able by config in case you don't want it to do 127.0.0.1 ? Something like this but also skip it if a var like mentioned here #91 is set to no?

[radeksimko]

This went off my radar somehow, so the branch had some conflicts, but I just rebased it.

The idea in #91 isn't bad, but I would personally expect this to work out of the box (i.e. w/out any specific DSL option). Is there any harm that this "out-of-the-box behaviour" may cause?

I think it's good as a default , even if you had other networks. I would only want it disable if I set it like in #91 , i.e. if !localhostconfig = false then add 127.0.0.1

This would help me out since I have to use localhost due to my workplace VPN making non-localhost vagrant networks not work. What needs to happen to get this merged?

Merged.
