move validator strings before imagery in Launchpad

[aceman]

Please move validator strings before Imagery names in launchpad for translation.
Translators are much more likely to translate full JOSM core, but imagery and plugins may be left partly translated. It is hard to hunt for the validator messages if they are mixed in somewhere between imagery and plugins.
Actually move all core strings first and the imagery and plugins last on launchpad.
Yes I know there are plans to split out imagery and plugins into separate repos, but until that is done, the reordering would help us.
Thanks.

ATM Imagery translations is part of the core, which is also the reason why it is up-front. In [o34067:34068] I moved it behind validator and style, but it is still a part of the core!

It seems the strings I mean are in mapcss validator rules.

Replying to aceman:

That was clear. Direct validator strings are intermixed in the core software strings.
