MOHAWK: MYST: Make Dni/Atrus endings an enum

The global variable "ending" tracks various
states that Atrus can be in.

This variable determines what video of
Atrus will be playing and if the brother
books have been destroyed.

Despite this variable being called ending
there are other endings not captured by
this variable (like the brother endings).

Also change spelling of Dini to Dni for one
usage of ActiveAge from a previous commit.
