'selectsaved' extension

Instead of a menu listing
 a - hero1
 b - hero2
 n - New game
 q - Quit
show
 a - hero1-role1-race1-gend1-algn1
 b - hero2-role2-race2-gend2-algn2
 n - New game
 q - Quit
or
 a - - hero1-role1-race1-gend1-algn1
 b - X hero2-role2-race2-gend2-algn2
 c - D wizard-role3-race3-gend3-algn3
 n - New game
 q - Quit
when any game in the list wasn't saved during normal play.  (Those
are sorted by character name; the playmode is just coincidence.)

The dash for 'normal' doesn't look great but -/X/D are codes used in
entries written to paniclog.  The whole playmode prefix doesn't look
particularly good but I suspect that most players relying on restore
via menu won't see it.

It should work when the character name has dashes in it but that
hasn't been properly tested.

The gender and alignment suffices reflect their value at the time of
save rather than at the start of the game.  That might be considered
a bug but it was easiest.

Increments EDITLEVEL; existing save and bones files are invalidated.
