As of this commit, do not consider the experience when playing that new
expansion to be complete. I've only partially written some of the mission texts
and rudimentarily enhanced some boss fights.
Currently there is one major limitation in that the intermission texts cannot
be replaced, as they're hardcoded inside the UMAPINFO. I don't know if I can
work around that.
+ Invinciball activation now voiced by Demo (thanks, Vyolette).
+ Retooled exit line merging (should fix those pesky duplicate exit markers).
Note: Oneliners for the Eviternity 2 final boss are not voiced yet.
