X9 update

x9 enhancment ideas

• Convert text files to database.
• Add shortcuts for common operations (e.g., move emulator between two hosts/targets).
• Auto reserve linked items (tfhost, lauterbach, etc)
• history (e.g. last locked)
• history of configuration changes
• history of target usage
  • will help know which lauterbach may be best to move
• report showing items left on but not reserved
• Auto restart x9 when it crashes (?)
