Title: Set default write concern for MongoDB

Set default write concern for MongoDB to safe to assure things are synced properly and to remove ugly warning message for newer versions of MongoDB:

Please ensure that you set the default write concern for the database by setting
one of the options

w: (value of > -1 or the string 'majority'), where < 1 means
no write acknowlegement
journal: true/false, wait for flush to journal before acknowlegement
fsync: true/false, wait for flush to file system before acknowlegement

For backward compatibility safe is still supported and
allows values of [true | false | {j:true} | {w:n, wtimeout:n} | {fsync:true}]
the default value is false which means the driver receives does not
return the information of the success/error of the insert/update/remove

ex: new Db(new Server('localhost', 27017), {safe:false})

http://www.mongodb.org/display/DOCS/getLastError+Command

The default of no acknowlegement will change in the very near future

This message will disappear when the default safe is set on the driver Db
