Modification for changes to the field "MetacatUtil.skinconfigs".

Changes to the field "skinconfigs":
1) Made it private
2) Created setter and getter methods
3) Created a 'hasSkinConfig' method

fix mistake where there is an attempt to select nodetype column from table xml_path_index table (it's not there!)

changes for fix to bug #2999 (only one attribute of an element is returned in resultset doc)
-added merging for large TEXT nodes when they have been broken up.
-allow multiple attributes to be returned in the resultset doc (uses newly-available field type to determine text vs attribute node).

add retrieval of field type for each node (TEXT, ATTRIBUTE, etc).
this is to support a fix for bug#2999

Fixed a couple of bugs: 1) Threw an error when updating a packages public access (lost the data files doc id's) and 2) returns a message after access is changed.
Both were fixed by not attempting to get a child text node from a text node.

Changed confirm.jspx to confirm.jsp

Modified redirect URL to navigate to a skin-specific confirmation page, rather than a common one.
