Metacat

Modified the build.xml to include a new task for building the dataone
service api package, which generates a jar file that is put into lib. This
task depends on maven being installed in maven.home, and depends on the
DataONE service_api being checed out in a sibling directory to the build....

Updated the build to properly locate the servlet jar depending on which
version of tomcat is being used, tomcat5 or tomcat6.

Refactored putObject method to separate the create() and update() portions in order to match the method signatures needed for DataONE.

Modified ResourceHandler.deleteObject() to take a globally unique id (guid)
as input rather than a metacat-conformant docid. The guid is translated
into a metacat docid which is then used in the handleDelete() call. So now
Metacat supports use of arbitrary identifiers for delete operations, but...

Added support to ResourceHandler to allow the putObject method to use
arbitrary guid strings as input. These strings are examined, and if they
match the Metacat docid format (scope.id.rev), they are used directly. If
the id is a string in another format, a new localId is generated based on...

Adding a new property to be used as an identifier prefix by default.

Updated MetacatRestClientTest so that the tests are actually calling fail()
when errors occur, and fixed all sixteen tests so that they run successfully
and can be run from any client (i.e., they don't depend on particular
documents being present in Metacat). The 'restfiles' directory can probably ...

Fixed bug in getNextRevision() where "error" documents were not being
detected properly before searching for the next identifier.
