Metacat

Some refactoring of the printExtendedSQL()
methods to eliminate redundancy in the code and
to provide more readable documentation.

Moved decision about whether to use xml_index for
query to the metacat.properties as "usexmlindex". Default
is now false. Still have some refactoring to do to remove a
few more uses of the xml_index table.

Replaced properties file that I accidentally overwrote. Reverting to 1.3.

Removed unused references to abstractpath, and some unudes javascript.

Created new printExtendedSQL function that can get the extended
return fields using only xml_nodes and not xml_index. One
step closer to eliminating the dependence ofn xml_index.

Created test class QuerySpecificationTest and started process of removing the xml_index from the QuerySpecification code. Reformatted some classes for readability.

Removed the "getdataguide" action as it was always experimental and is no longer used in metacat or morpho.

removed the 3 versions of printPackageSQL which are no longer used by metacat. This eliminates some dependency on xml_index.
