FS#523 - Proper media/ribbon status messages

CUPS has a standard reporting mechanism for attributes, including media/ribbon/etc levels. The general syntax is:

ATTR: foo=bar[,baz,etc]

There's also the notion of state that can be reported in a unified manner:

STATE: +media-empty [reasontext]
STATE: -media-empty


1) Altering backends to report media empty using this mechanism
2) Alter backends to report remaining media, if known, using this mechanism.

For further details:

The core work is in, and most backends now report the remaining media as a (occasionally guessimated) percentage.

Error reporting and other state management is still not being done with this mechanism though. That'll come later.

All backends (except for kodak1400 and shinkos1245) now report some sort of marker status. Either:

* accurate (!) percentage
* "unknown but ok" vs "0"

kodak1400 will probably never become intelligent enough for this (we simply don't have sufficient info about loaded media or any sort of counters), but shinkos1245 should be able to infer what we need once I come up with a reliable way to guess at the loaded media type.
