Stargate sims unified

After much discussion on the forums, Ash Leighton Plom has combined the three Stargate sims we had, two of which were inactive, into one single sim called Stargate: Beta Site. The idea was originally proposed by a player who has now left the site, but his good idea carries on.

This sim will continue in the Season 9/10 Stargate SG-1 setting it had previously, with Ash remaining in overall charge.
