[RLVa] f9f8dbe23ec3 ported

- internal : reviewed @startim for CHUI (SL-3.5)
    -> fixed : "Start Conference Chat" on a selection of multiple calling cards opens an IM session
    -> fixed : actions that would result in an IM window opening shouldn't be blocked if the session is already open
    -> added : RlvActions class to mimick LLAvatarActions and lowering the rlvhandler.h include dependency
