Metacat

Added warning to be displayed in the log when document is not inserted.

1. useSiteCoord option is made avaiable again

Interim checkin -- getting the postgis database setup

Added lter to list of orgs.

New changes in the esa skin so that includes the moderator functionality and login/logout functionality

These are all header updates to include the login and logout for the ESA Header links. I left the original Header and named it headerOld.html and saved the Slices
that go with it too. (the ESAHomeLogo.gif file might be overwritten) The code for
the header to work with the Logout slice and roll over is in the file headerLogout.htm. <td><a href="#" target="_top" onMouseOut="MM_swapImgRestore();" onMouseOver="MM_swapImage('ESALogout','','ESAHeaderSlices/RollOvers/ESALogoutR.gif',1);"><img name="ESALogout" src="ESAHeaderSlices/ESALogout.gif" width="57" height="17" border="0" alt="Logout"></a></td> The code for the login slice and rollover is in the header.htm file <td><a href="#" target="_top" onMouseOut="MM_swapImgRestore();" onMouseOver="MM_swapImage('ESALogin','','ESAHeaderSlices/RollOvers/ESALoginR.gif',1);"><img name="ESALogin" src="ESAHeaderSlices/ESALogin.gif" width="57" height="17" border="0" alt="Login"></a></td>

Modified the login method in the perl metacat client so that status of the user logging is also returned
Earlier if login info was not valid, 0 was returned. And 1 is sent back if login info was valid.

Now, if valid then following values are returned to indicate user status...

Added support in the metacat client for the new function added to MetaCatServlet

Added a new action - getloggedinuserinfo - which returns information about the user in the following format.

<user>
<username>uid=sgarg,o=NCEAS,dc=ecoinformatics,dc=org</username>
<name>Saurabh Garg</name>
<isAdministrator/>
<isMOderator/>
</user>
