[FEATURE REQUEST] Add some more fields in the message

[sbrunner]

I started the support of Prospector in vscode-linter
fnando/vscode-linter#47

And I see that we have some missing information in the message:
line_end, character_end, doc_url and is_fixable.

Think that we should add this information to the Message (Location) object, use the in the JSON output.

We probably also need to add a --no-fix command line options.

Example of Pylint output:

   {
       "type": "convention",
       "module": "test",
       "obj": "aaBbb",
       "line": 22,
       "column": 0,
       "endLine": 22,
       "endColumn": 9,
       "path": "test.py",
       "symbol": "invalid-name",
       "message": "Function name \"aaBbb\" doesn't conform to snake_case naming style",
       "message-id": "C0103"
   }
