[r=jtv][bug=812667] Don't say a distroseries "derives from" its previous_series.

= Summary =

The DistroSeries listings still say that a series "derives from" its previous_series. But distro derivation now assigns a very specific meaning to that term that has nothing to do with previous_series.

== Proposed fix ==

Say "successor to" instead of "derives from."

== Pre-implementation notes ==

StevenK did not like this wording: it "doesn't really do it for" him. Alternatives that have been considered:

 * "Based on" — too generic, would cover derivation just as well.
 * "Previous release" — in this context, makes it look like a previous release _of the series_.
 * "Supersede" — but is that always accurate?

We do need to get away from "derives from," however.

== Implementation details ==

We may still choose to change the wording. It's pretty much a copy-paste job to this branch. There is one other place where the wording will be affected once we retire the feature flag for the distro-derivation UI.

== Tests ==

{{{
./bin/test lp.registry -t xx-distroseries-index
}}}

== Demo and Q/A ==

Browse to /ubuntu/+series and look at the series descriptions. There should now be a clear, sensible distinction between succession and derivation.
