Base Command.

> All your base are belong to us.

All commands should inherit from the base `Command` object.

This object handles the dependency injection of the `phonegap` object.

This has two major benefits:
  1. Allows `PhoneGap` to create instances. This is helpful for testing.
  2. Allows test framework to mock public interfaces during tests.

Options:

  - `phonegap` {Object} is the instance of `PhoneGap` for this command.

Returns:

  {Function} that will call the inheriting class' `run` function.
