[Talk-ca] Fixed version of JOSM to ease Canvec merges

[Tyler Gunn]

JOSM previously had the ability to "fix" the duplicate nodes present
where canvec tiles join one another, but in recent versions appears to
have removed that capability.

Based on a bug I found in the JOSM bug tracker, I created a patch to
re-enable this functionality:
http://www.egunn.com/osm/canvec_fix_nodes_osm.patch

If anyone is interested in a compiled JAR file for JOSM with this
patch applied, let me know and I can send you a link.
It makes merging in the canvec tiles a LOT easier (no manual selecting
of duplicate nodes and merging).

Thanks,
Tyler
