Add obsolesence reasons (and comments?) to obsoletes table?

[matentzn]

Add obsolesence reasons (and comments?) to obsoletes table to make it a bit more informative? Perhaps even aggregated xrefs?

I think for the obsoleted comment the following fields would be interesting:

• obsolescence reason
• consider
• consider label
• replaced by
• replaced by label (if possible)
• comment
• comment (often, a lot of interesting stuff is hidden in there!)
• xrefs

generally, 1 row per obsolete class, and where there are multiple values of the attributes above, just roll them into a pipe-separated string.

FYI I know this because I just generated some similar, ad hoc report, the predicate for obsolescence reason is IAO_0000231.
