Message:

Large rework in projection handling - now allows only switching and more specific projections
TODO:

• allow subprojections (i.e. settings for projections)
• setup preferences for subprojections
• better support of the new projection depending world bounds (how to handle valid data outside of world)
• do not allow to zoom out of the world - zoom should stop when whole world is displayed
• fix Lambert and SwissGrid to handle new OutOfWorld style and subprojections
• fix new UTM projection
• handle layers with fixed projection on projection change
• allow easier projection switching (e.g. in menu)

NOTE:
This checkin very likely will cause problems. Please report or fix them. Older plugins may have trouble. The SVN plugins
have been fixed but may have problems nevertheless. This is a BIG change, but will make JOSMs internal structure much cleaner
and reduce lots of projection related problems.
