Add a Package to the Kit

[zburns]

I'm trying to get the NoCatSplash package into DD-WRT micro.  I don't need a lot of space at all and think I can accomplish this.  I've got the firmware kit installed and it will re-compile a new version.  My question is how would I put the nocatsplash binary into the sbin folder so it works correctly.  Can anybody give me a clue?
