Support MULTI command

[marinoaldi]

Feature Description

@sagiegurari congratulations for your lib! It is just what I was looking for.

But... what about support MULTI command? Would it take a lot of work to implement it? If you have thought of any idea of how to do it, I could help you implement it.

Thanks in advance

thanks! ya, I do not support MULTI (see limitations section which is strange not to support multi in a project named multi.... :D

However, looking at node redis today, it might not be that hard to implement.
I'll take a look at it or if you want you can push a PR (up to you).
It shouldn't be too hard (without investigating too much), as the Multi gets a redis client in the constructor, so the multi redis server implementation which is in the client would automatically apply by the Multi instance which uses that client (I'm wring multi too many times, so I hope the high level explanation is semi clear).
But... its really from looking 2 seconds at node-redis code.
