Service command handling fix when no upstart config file

    Fixed the service command not working

    On Ubuntu 1[02].04 the service name was not recognized because
    there is a SysV style init script, but not an upstart config file.

    Example: The `ntp` client.

    Also removed extra spaces at the end of the lines, while at it.

Fix proxy env format

The incorrect format (e.g. http_proxy=http://proxy.bos.example.com:8080) gave this error: "environment must be a dictionary".

Fix CliRunnerCallbacks.on_file_diff in callbacks.py

When running ansible -C, I get a traceback that ends with
    AttributeError: Values instance has no attribute 'diff'
This fixes on_file_diff to behave similar to
PlaybookRunnerCallbacks.on_file_diff().

This updates the following modules to support check_mode:
* apt_key
* apt_repository
* easy_install
* pip - will always report changed due to the way it handles state
* seboolean
* selinux
* slurp - since nothing changes, it just adds that it supports
  check_mode
* subversion - reports changed when checking out new repo and
  when updating.
* supervisorctl
* svr4pkg

See issue #2114.

Fixes #2218.
