IM mostly fixed according to Brian's directions. Will need to do some additional option handling and cleanups

server-tools/instance-manager/Makefile.am:
  New file added
server-tools/instance-manager/client_func.c:
  typo fixed
server-tools/instance-manager/commands.cc:
  there are no admin-user snd admin-password fields anymore, so no need to show their values
server-tools/instance-manager/guardian.cc:
  Syncronization added -- now guardian wakes up whenever SIGCLD has been catched
server-tools/instance-manager/guardian.h:
  Condition variable declared
server-tools/instance-manager/instance.cc:
  Persistent connection to the instance removed. Now we use SIGTERM instead of com_shutdown for STOP. We also
  manage SIGCHLD ourselves now (therefore no double fork).
server-tools/instance-manager/instance.h:
  Pointer to the instance_map added, MySQL connection structures removed
server-tools/instance-manager/instance_map.cc:
  More syncronization added (to make proper STOP)
server-tools/instance-manager/instance_map.h:
  added condition variable and mutex for connection threads to wait for SIGCHLD
server-tools/instance-manager/instance_options.cc:
  defaults-handling methods have been added.
server-tools/instance-manager/instance_options.h:
  New functions and constants declared
server-tools/instance-manager/listener.cc:
  No changes here (bk bug?)
server-tools/instance-manager/manager.cc:
  SIGCHLD handling added
