Fixed Mac deployment compiler warning (uninitialized memory read, but in unused code).  Reviewed with Steve long ago.

SL-39721 Run a mini-grid without editing any configuration files.  Added start-servers.py and start-client.py.  Renamed output executable names to "spaceserver" instead of "newspace", etc.  Repaired batch files to use new executable names.  Added svn ignores for new executables and intermediate files.  Removed llcommon, other linden libraries from explicit linker Additional Dependencies section because this makes IncrediBuild link the libraries twice, slowing it down.  Reviewed by Don.
