added the MAC address to vendor tool to apropos

A while ago I put together a little tool
that maps EUI-48 and EUI-64 Media Access Control ( MAC ) addresses to Vendors
eg 00:00:0C:DE:FE:DC

I just added it to apropos
and it works with : and - delimiters
eg 00:00:08:02:11:B0 or 00:00:08:02:11:a0

MAC to Vendor from apropos
