Express-session-mongo should be connect-session-mongo

[bartt]

Hi Dav,

I like what you've created here. But.. it is session support is part of connect not express. As express builds on connect it might have appeared to be part of connect. Ergo the name is a bit misleading and the dependency on express can be removed.

I would have submitted a patch but in this case the name of the repository has to change which I don't think is possible with a fork. And I'd hate to create a nearly identical connect-session-mongo just to correct the needless dependency.

Any chance you'd be willing to replace express-session-mongo with connect-session-mongo?
