Define isomorphic mapping between OME and OMERO.blitz.

[jmoore]

There needs to be a one-to-one mapping between the types that are passed through the ome.api.* interfaces and what's defined in the *.ice files. There are several ways to do this:

• Generate the *.ice files
• Add annotations to the ome.api.* classes
• Have the definitions in an external *.properties files

Currently, however, this is being done solely through the IceMethodInvoker class.

Taking this out of a iteration. It will be an ongoing process. r1353 gets us one step closer.

As in #613, this seems to be largely done. (Issues may still exist.) See omero/util/IceMapper on how all this works. Documentation is still needed.
