[josm-dev] JOSM 7777 released, with the new logo + help needed for an OSM blog post

[Bryce Nesbitt]

I did a little bit of work on the Mac setup instructions on the wiki.

Since even OS X Yosemite (the latest version from Apple) includes Java 6,
the setup for JOSM is quite involved for Mac users.  Some more work on
this issue
is definitely needed, especially if the hope is to draft in more new
users to JOSM.
