#22 getInterface function for multicast on multiple interfaces

[Phil Ingram]

I developed this code because my fog server has an 802.1q trunked presence on all networks and multicasting by default only binds to 1 interface. This code finds out which interface has the ip/hostname of the master nfs server and makes this the interface to which the multicast udp-sender binds to.

this is my very first code submission ever and until last night i had very little experience with php/mysql - but i have been making simple perl scripts for years. While this may be ugly looking it works and does so consistently.

fog rocks, keep up the good work.
