oauth2-server isn't chopping \n characters from lines read from $stdin.gets

[bploetz]

When running oauth2-server, many of the values collected on the command line end up looking like this in the database:

{ "_id" : ObjectId("4d81ce61f1ea7ea4cf999991"), "display_name" : "foo\n", "link" : "http://www.foo.com\n",

Note the \n characters. IO#gets includes the line separator in the line it reads. oauth2-server should chop the string read from $stdin.gets before storing it in the database to remove the trailing \n character
