Clean up OmeroJava (see #11274) (rebased onto develop)


This is the same as gh-1422 but rebased onto develop.

----

This PR 
- moves the unit tests from OmeroJava to blitz and fixes the build,
- standardises whitespace usage in all the packages (code template used: ``docs/styles/OMERO_Eclipse_Code_Style.xml``),
- increases the TestNG test timeout from 30 to 120 seconds.

To test - run the integration tests locally (no job yet) with ``./build.py -f components/tools/OmeroJava/build.xml integration``. Remember to set ICE_CONFIG to point to a valid file. 
Especially, there shouldn't be any failures with the message ``Method org.testng.internal.TestNGMethod.testGetParams() didn't finish within the time-out 30000``.

Before this PR there were 682 tests on ``develop``. This PR reduces this to 656, as the unit tests (besides ``BlockSizeTest``) have been moved to blitz. Ergo - no tests have been excluded from the run (besides broken ones, in their own group).
