JP1 Remotes

I don't normally post when I create an upgrade, in this case for the SP4805 but I thought Rob and others might want to update their generic InFocus files with some new labels:

Brightness Up -- OBC 3
Brightness Down -- OBC 7

and some additional functions:

Volume Down -- OBC 4
Volume UP --- OBC 8
Blank (no input) -- OBC 49

and 2 alternative commands:

Direct Source 1 -- OBC 25
Direct Source 2 -- OBC26

The upgrade only includes the commands my Projector responded to, up to OBC 64.
