Metacat

remove very old "metacat webservice" code - as far as i can tell it is never referenced or used. plus we have eocgrid and the new D1 rest services covering this territory now

removed newline addition to test doc now that the newline problem is fixed in utilities project. Small adjustments to comments and debug statements to aid in debugging. Reordered tests to remove possible insertion between read and getLastDocid test.

zero padded date string in DocumentUtil.generateDocumentId() for readability

Use SystemUtil.getContextURL() in ResourceHandler to construct the DataONE service URL (rather than direct calls to PropertyService). This handles http and https URLs, and strips the :80 or :443 for the well known ports.

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
