[mb-devel] Release date/locations

[Olivier]

1 - It would have to be done on a track by track basis, not release basis.
2 - a track may be recorded on several days (multiple takes then
spliced), including for live that later receive an overdubbed part
3 - such a "date" already implictely exists, as the engineer AR
(recorded by) is a temporal AR
4 - other dates may be used on other engineer roles as well

IMO, recording dates are intrinsically linked with "recorded by" AR,
and should be kept there.

As for the locations, it sure would be a very fine addition.

Hope I make sense...
