   key_handle_key_press now handles all the key presses and history_keypress is
   now defunct. It goes thru the linked list keys_root and finds a matching
   key. It runs the action func and switches on these values:
   0) Return
   1) Find next
   2) stop signal and return

   * history_keypress is now dead (and gone)
   * key_handle_key_press now takes its role
   * All the possible actions are in a struct called key_actions (in fkeys.c)
   * it is made of {function, name, desc}
   * key bindings can pass 2 *text* strings to the handler. If more options are nee
   ded a format can be put on one of these options
   * key actions are passed {
   the entry widget
   the Gdk event
   data 1
   data 2
   session struct
   }
   * key bindings are stored in a linked list of key_binding structs
   * which looks like {
   int keyval;  GDK keynumber
   char *keyname;  String with the name of the function 
   int action;  Index into key_actions 
   int mod; Flags of STATE_* above 
   char *data1, *data2;  Pointers to strings, these must be freed
