wireless NIC detect at install
I'm definitely not great at writing scripts, but this worked for me with one wireless card and one ethernet NIC. For now it assumes there is one of each and the wireless is the external interface. maybe someone can take this and make it more robust or universal.
I do not have a setup with two ethernet NICs to verify it didnt change anything.
I modified mce-install.sh. This worked for me assuming i was already connected to the wireless net prior to install.
