Metacat

Make this class be the subclass of the MCTestCase. The super class will initialize the property service for it.

Minor changes to MetacatHandler:
- Improved logging where MetaCatServlet.class was used in getLogger() rather than MetacatHandler.class (holdover from the refactor)
- Minor formatting changes, and replacement of 'MetaCatServlet' with 'MetacatHandler' in the logging output as needed.

commenting out the pisco user tests, since they only work in production.

put in more explanatory exception methods in the private helper functions that throw exceptions, and some debug statements in the onlineData201CasesTest_1 test.

improved multipart handling (improved logging messages, code, and error checking). Added exception classname to error output when the generic Exception is thrown. Added error check for cases of null value for file parts 'sysmeta' and 'object.'

added a few debugging lines in createSystemMetadata() related to contents of identifier strings

Due to changes in MetacatHandler that creates system metadata from uploaded EML documents, OnlineDataAccessTest was failing certain tests because of errors in how the test documents were originally uploaded. MetacatHandler.createSystemMetadata() was throwing exceptions because of these errors, specifically when a data document is uploaded with a docid that is difeerent than the docid statement in the EML distribution URL. Most errors involved stated docids with .2 versions, and the metadata had .1 versions....

Modified IdentifierManager.getDocumentInfo() to include the docid in the returned hash map, since it is useful to be able to obtain the docid and rev separately from a given fullDocidWithRev (e.g. test.1.1).

fixing annoying error message inaccuracy

Cleaned up imports.
