RLVa: Add @sitground functionality to RLVa

Description

Hey,

I'm currently working on a project which makes use of the @sitground command which is present in Marine's RLV (ver. 2.9.29 and above), but this feature is missing in RLVa - I'd rather not have to try and re-engineer another fix just for RLVa compatibility, so I'd definitely like this added please!
