Previously, the Version resource used by Version.java was compiled
directly into the war, rather than being included in the java_library
alongside the class that used it. The intended effect was to produce a
version of "(dev)" when running from Eclipse, and an accurate version
when running from the war. However, it made the build graph a little
confusing, and moreover made it impossible to write a test that tests
the actual format of the "git describe" output.
Rearrange the build rules to include Version in the common:server
library. This actually still results in "(dev)" when run from Eclipse,
because there is no jar for this library in the Eclipse classpath, so
looking up the resource will still fail as expected.
