Feature request: Make the the sbbs_t open message base (smb_t) writable via JS (to allow changing bbs.msg_number, bbs.smb_curmsg, and related)

For quite a while, when replying to a message, SlyEdit has had the ability to get the author's initials from the message the user is replying to, in order to quote the message with that message's author's initials. Normally, SlyEdit gets the current sub-board code & message number from bbs.smb_sub_code and bbs.msg_number (if > 0) or bbs.smb_curmsg. However, when using my message reader (DDMsgReader), bbs.msg_number, bbs.smb_curmsg, and related are read-only, so DDMsgReader can't set them to pass along that information to a message editor (such as SlyEdit) that might want to use those.

DDMsgReader currently writes a drop file with this information so that SlyEdit can read it, but I don't think that's the best solution.
