EternalJK hasn't been updated in years, let's use Vanilla OpenJK for JAMP

[athendrix]

So, OpenJK which is used for the SP of Jedi Outcast and Jedi Academy is continuously updated, while EternalJK used for the Jedi Academy Multiplayer hasn't been updated in years.
It also seems to change the types of games that can be joined.
I have a server on my local network that can be joined with standard Steam Jedi Academy, as well as OpenJK, but not with Luxtorpeda's EternalJK.
So while EternalJK is nice, I think a more maintained, more vanilla option like standard OpenJK would be more appropriate for general Linux use.

@athendrix I maintain an active fork of luxtorpeda (https://github.com/luxtorpeda-dev/packages/issues), if you're interested you can create an issue there. With the new features, I could provide options for openjk or eternaljk.
