Uniaud Documentation

[lewisr]

Currently, the only documentation for Uniaud comes in the form a readme text file. My impression is that few people bother getting more than halfway down through the file, and it does not serve as a handy local reference due to its text format.

I propose migrating much of the standard text in the current readme to a .inf, and reserving the readme for changes and updates. Ultimately, unimix documentation should be included in the reference documentation (see ticket #142).

The component on this ticket should be "Docuemntation" and this will be recharacterized when that category is available.
