OMR Spec - Updated 8/22

[Orion Pobursky]

The point is to have each file inside the MPD have a unique name. This is for file tracking purposes and to prevent file overlap if the MPDs are unrolled in 1 directory. As far as part naming, I'm trying to make this spec as loose as possible while still preserving some structure. This will allow more submissions in a shorter amount of time and not discourage the non-technical form submitting files.
