Configure Eclipse to compile/copy each plugin's classes and resources
into its own private classes folder. This should fix the duplicate
resource warnings for about.md or other documentation and static image
assets.
Move test and utility classes into their own directories too. This
has no real impact on the runtime classpath at this time, but opens
the door to do something more creative later.
