add device plugin

Adds the ability to sniff what kind of device is running and it's OS
version.
Important for cross browser quirks.

`cordova plugin add org.apache.cordova.device`
add splash screen plugin

Allows us to programmatically  show/hide the splash screen. This is nice
for Meteor Rider since the phonegap 'ready' event fires before
MeteorRider
or your Meteor app is really ready.

`cordova plugin add
https://git-wip-us.apache.org/repos/asf/cordova-plugin-splashscreen.git`
build ios for new plugins

runs `cordova build ios` to compile new plugins into iOS project.
copy meteor rider files

download zip/clone from https://github.com/zeroasterisk/MeteorRider

Cordova now uses `cordova.js` without a version number. Updates this to
get MeteorRider working.
