- internal : reviewed @startim for CHUI (SL-3.5)

    -> fixed : "Send Instant Message" on a calling card opens an IM session
    -> 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
