Metacat

Fixed bug with file updating (lost qformat value). Also fixed bug with message.

Change the debug level for Metacat initialization message.

Converted some java 1.5 code to java 1.4 code. Removed usages of "String.contains()", "Node.getTextContent()" and "Node.setTextContent.

Converted some java 1.5 code to java 1.4 code. Removed usages of "String.contains()", "Node.getTextContent()" and "Node.setTextContent.
Wrote two new methods: 1) getTextContent, and 2) setTextContent, to emulate the org.w3c.dom implementation that ships with java 1.5.

Seperated web API code, from plain java code, by creating seperate constructors and handling Http stuff in just two methods: "clientRequest" and "handleDownloadResponse".
Results in using HttpServlet code in an isolated/thin layer, making it easier to test and reuse all other methods.

Added new functionality for action="Set Access". Includes methods handleChangeAccess, setPublicAccess and getNodeTextStack. Also, cleaned up some code as a result.

Modified string constant "SUB_DOCS_PATH" to be static and public accessible.

Added param to indicate if public has read access or not, in the method "readFromMetacat". It only does this if reading a metadata document, for a skin-format,
and the user is not public. This is useful to the skin's metadata display/editing form, for indicating public accessiblity (or inaccessibility)....

Fixed bug where the Permission Order was always being set to 'allowFirst'.
It was comparing against the constant AccessControlInterface.DENYFIRST with the variable name surrounded by quotes. Removed the quotes and updated comments.

Modified a sql command from "like" to "=". It dramatically improves the peformance of build index.
