Getting device ID in disk drive regardless of item type

[Ale32bit]

As of now the function disk.getDiskID returns the ID of the item in the drive, but only if the item is a disk.

What this feature request suggests is returning the ID of the drive-compatible item regardless of the type (disk, computer, turtle, pocket computer).
In addition to this, to avoid ID collisions, a new function can be introduced to return the type of the item, I.E. disk.getItemType.

Some rationale/use case for a feature. My general approach to designing new features is to ask yourself "what issue are we trying to solve" and then "is this the best way to solve this issue?".

I think it would perhaps be useful to have some additional context here. One of the struggles I have with both this issue and #634 is that I'm not sure what you're really trying to solve here - is this just for display purposes, or something else?

Personally I kinda feel getDiskID (or indeed exposing them user-side at all) was a bit of a mistake. For computers it makes sense - ids are needed for rednet - but less so for anything else.
