Gnome basic functionality

- let the "#" key work as per Guidebook
- role selection didn't work if you had gender specified in your .nethackrc
  similar problems would occur for other .nethackrc selections
- fix an obvious memory leak
- fix one crash bug from accessing a freed pointer (M-? dismiss M-?)
- note some invalid behavior in comments for a real Gnome developer to fix
- reformatted some code so I could follow it
