Extend release preference with comparison options

[Nikolai Demiankov]

Original idea came from nordnet/cordova-hot-code-push#108. By default releases are compared as strings. But in some situations we need to install only newer releases. So, need to add support for logic like this in chcp.json:

{
 ...
  "release": {
    "version": "2016.02.18-16.47.12",
    "compare": ">"
  }
}
