Metacat

fix tests:
-insert default objectFormatList from d1_common (includes schemaLocation now)
-calculate checksum for the system metadata using the ChecksumUtil in d1_common

prepared statement toString() does not include quotes (') around the inserted values -- now the test reflects this.

Metacat now keeps track of permissions on a per-version basis -- the test reflects this change in behavior.

refactor Metacat access handling to be on a per-revision basis so that it more closely aligns with the DataONE approach

update test to reflect newer change:
handle queries with predicates correctly.
when docids are used in the return field look up, we need to make sure they are included in the values in the correct order for their corresponding parameter place holders (?)

Add new test method to test getAccessControl.

catch all possible exceptions

act as a registered CN when calling CN methods -- create(), for example, is restricted to only be callable by a node of type CN.

use IOUtils for testing read/write of XML strings. This goes along with the utilities project change to use the same apache commons IO library. Be sure to clean the utilities checkout in order to catch the right utilities svn tag when building!

when comparing D1 Subject objects, use the equals() method not direct string comparison
