Make Imagery offset correction options default or at least more prominent

[RicoZ]

The offset database with the plugin (​http://wiki.openstreetmap.org/wiki/Imagery_Offset_Database) are very helpful to reduce systematic errors introduced by skewed aerial imagery (most notably Bing).

Even as an halfway experienced contributor I do occasionally forget to activate it, there was also a recent discussion on the talk-de mailing list about the possibilities.

I could imagine following approach: when activating Imagery/Bing, present the user with the following dialog:

• download imagery offset from database
• correct offset manually
• ignore for now
• ignore allways
• further informations - ​http://wiki.openstreetmap.org/wiki/Imagery_Offset_Database

Correcting imagery offsets is important but very often forgotten.

Notes for the future:

• ​https://github.com/Zverik/iodb (website backend, WTFPL)

I believe we try to avoid calling non-JOSM/OSM websites by default (exceptions are only after the user makes a choice, e.g. enabling a plugin/preset/validator or enabling an imagery layer).

And I don't know if the server admins want to maintain another service.

TBH, this ticket seems to be about moving the imagery_offset_db plugin into core, and getting offsets by default.
