Update of /home/minion/cvsroot/src/minion
In directory moria.mit.edu:/tmp/cvs-serv20799

Modified Files:
	TODO 
Log Message:
Start improve list-servers; refactor config types; less mem usage for flush.

ClientDirectory,ClientMain:
 - New interface to display server information.  Not done yet, but
   better than groveling over directories by hand.

ClientMain, MMTPClient, ClientUtils:
 - Change client queue flushing code so that we don't load everything
   into memory when we flush the queue.  Moved ClientQueue to use a
   metadata store; added proxy class to lazy-load flushable messages
   without changing sendMessages interface.

Config:
 - Add resolveFeature/getFeature functions to generic config file
   interface to make it easier for users to describe aspects of server
   descriptors.

Config, ServerInfo, test, Modules, ServerConfig
 - Change the way that types are specficied for _ConfigFile
   derivitives: now they're by name instead of by by function.  This
   makes unparsing a snap, and keeps us from having to use private
   (underscore-prefixed) names from Config.
