Metacat

Updated install instructions with IPv6 instructions for postgres.

Changed default maxHarvests value to 0. Added logic to ignore maxHarvests value when it is set to 0 or a negative number. This allows Harvester to run indefinitely without shutting down after reaching a maximum number of harvests. The previous default value of 30 would cause Harvester to terminate after 30 harvests.

Updated the diagram with terminology that is consistent with the current harvester design.

Modify Harvester documentation to provide instructions for configuring and running Harvester as a servlet.

Minor enhancement to support multiple email addresses for harvester administrator and site contact. Each address is separated by a comma or semicolon.

One last clarification to the install instructions regarding the sql scripts.

Modified the build to be smarter about making sure that the EML schemas
and styles are in place (so manually running 'geteml' should no longer
be needed), and renamed the 'loaddtdschemas' target to 'register-schemas'.
Reorganized and clarified installation instructions to make the order of...

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.

Updated metacat documentation with additional properties and fixed the
description of several properties. We really need to clean out unused
properties and generally clean up the configuration morass.
