mongo objectID for the relations

[hoomanna]

I make some changes to make this driver work with object id.
also, because some database still use mongoID as string for relations I add options to use objectID or not (default is not).

 'mongoid' => true, // sets to use mongoID object instead of mongoID as string in relations.

Can we get this implemented? Relationships should use MongoId.

Currently reviewing your PR. Will probably have to tag a new major version though.

[amiri27]

@rtler Could you please solve the conflicts?

[gnrcampos]

Any progress on this? Depending on this merge to do some things, can I help in any way?

[jenssegers]

Well thing is, the new v3 release will bring support for the new mongodb PHP driver. I feel like doing both the driver and the mongo id's at the same time will break too many applications.

Current plan is to release v3 soon with the new driver, and work on a v4 featuring the mongo id's.

Also; because of the new mongodb driver, this PR is a bit outdated. So I can't really merge it into master.
