Metacat

New README in preparation for the 1.4.0 release, and updated the properties
file with the new version number.

Added in servlet action 'buildindex' for building the XML_index table entries

for the whole set of documents in the xml_documents table. The buildindex
action is restricted to only be accessible by users who are listed in the...

Created a list of all of the servlet actions in the documentation and listed
all reuired and optional parameters for each action. These need to be
documented but at least the list is all in one place now.

Added new sections to the Metacat documentation describing the Metacat
client API and the Metacat 'getlog' servlet action for event reporting.
