Title: Ablitity to set "w" parameter to a string in Connection.pm 

We need the ability to set the "w" parameter to a string. This is becaues as of 2.0, we can tell it to replicate to the "majority" of the nodes. Plus with tagging and data center awareness, we can create new "getLastErrorModes" to say who we want the data to replicate. Here are the docs about it:
http://www.mongodb.org/display/DOCS/getLastError+Command#getLastErrorCommand-majority
http://www.mongodb.org/display/DOCS/Data+Center+Awareness

I already created a bug report for it this time :)

Thanks.
