Update npm packages

[captainkirkby]

Some packages used by npm are not up to date. We will update them using nom

Package     Current  Wanted  Latest  Location
winston       0.7.3   0.7.3   0.8.3  winston
mongodb      1.3.23  1.3.23  1.4.26  mongodb
serialport    1.2.5   1.2.5  1.4.10  serialport
async         0.2.9   0.2.9   0.9.0  async
sprintf       0.1.3   0.1.3   0.1.5  sprintf
express       3.4.7   3.4.7  4.10.6  express
mongoose      3.8.3   3.8.3  3.8.21  mongoose

First update nom from the command line:

sudo npm install -g npm

Use this npm page to get versions right.

The carat (^) matches the version specified or a greater major release (^1.2.3 matches 1.4.5 not 1.1.1 or 2.0.0)

Testing now.

Here are the current dependencies:

    "dependencies": {
        "express"       : "^3.4.7",
        "async"         : "^0.2.9",
        "mongodb"       : "^1.3.23",
        "mongoose"      : "3.8.x",
        "serialport"    : "^1.2.5",
        "sprintf"       : "^0.1.3",
        "winston"       : "^0.7.3"
    }

Most recent mongoose 3.9 is unstable, so we force it to use 3.8
