Updated PushPlugin supports both ios7+ios8

This release fixes the startup event amongst others - For more details lookup the changelog.

We are currently still using a branched version of the cordova plugin and I had to update alot of the code in order to provide support for ios7+ios8.

Theres extra setting support in config.push.json a apn-dev option for setting credentials for development - this is used when the production flag is false

  "apn-dev": {
    "passphrase": "xxxxxxxxx",
    "key": "apnDevKey.pem",
    "cert": "apnDevCert.pem"
  },

Kind regards Morten (aka @raix)
