BridgeServer config changes

[Thomas D. Uram]

Changes I've made for this release include a change to the bridgeserver 
config file to the following:


# Overall bridge server configuration, including
# a port range that bridges should use
[BridgeServer]
name = Argonne
location = Chicago
qbexec = /usr/bin/QuickBridge
portMin = 20000
portMax = 24000

# A single venue with audio and video ports specified
[https://localhost:8000/Venues/default]
type = Venue
portMin = 24000
portMax = 24004

# A whole venue server
[https://localhost:8000/VenueServer]
type = VenueServer
 

This puts bridgeserver options, specification of multiple 
venues/venueservers, and the ports to use in a single file, whereas 
before it could be as many as three files.  The one issue I see is 
specification of ports _per media_ ; based on experience and comparison 
with other tools (the msb), how important is this option?  It should 
only be used outside of the AG2 software, so shouldn't be that 
important, but I wanted to point it out.  Let me know, too, if you see 
any other issues.
