Title: [PATCH] Added BITPOS operation

I added a `BITPOS` operation to Redis, which accepts `[start end limit]` arguments. As the name suggests, it operates on bit strings and returns the positions (offsets) of all the set bits. My C is a little rusty, so it might need a little review/improvements.
