[OSM-talk] JOSM landsat plugin -- Ability to move Landsat layer added

I have now added a facility to move the Landsat layer around in the JOSM 
landsat plugin.

If you have the Landsat plugin installed, an extra toolbar button will appear 
at the bottom of the modes toolbar when you open a GPX file or add data. If 
you select this button while you have Landsat loaded, you will be able to 
drag the Landsat around the map with the left mouse button, allowing you to 
adjust it so that it aligns with OSM data.

One significant issue is that if you click the new "Move landsat" toolbar 
button, the previous mode button you clicked (e.g. 'add node' or 'add 
segment') will remain selected, even though you're in 'move landsat' mode. 
This is due to the limitations of the JOSM plugin system; with the plugin 
system alone I am unable to add the new 'move landsat' button to the same 
button group as the other mode buttons.

That said, If you select 'add node' (or whatever) after you've finished 
adjusting the Landsat, you will successfully switch back to the previous 
mode.

Imi - I'd like to make two adjustments to the core JOSM code in order to give 
more flexibility to plugin developers. Is this OK?

1. Allow plugin developers to access the ButtonGroup that the mode buttons in 
JOSM are members of.
2. Allow plugin developers to override the default order of rendering nodes, 
segments, and ways; this will allow areas to be drawn first, then nodes, then 
non-area ways.
