add ability to extend parser settings

[kerbyfc]

Hi, i know nothing about sublime text plugin architecture, but i'll be happy to have an ability to use codo with this plugin. There are minimal (but may be not valid) changes to make it possible.

My use case for codo:

  #<enter>
  render: ->
    <div>LDAP VIEW</div>

  # becomes

  #
  # [render description]
  # @return {[type]} [description]
  #
  render: ->
    <div>LDAP VIEW</div> 

Keymap:

    // open a docblock with enter
    {
        "keys": [
            "enter"
        ], 
        "command": "jsdocs",
        "args": {
            "prefix": "#",
            "options": {
                "commentCloser": "#"
            }
        },
        "context": [
            { 
                "key": "setting.auto_indent",
                "operator": "equal",
                "operand": true,
                "match_all": true 
            },
            { 
                "key": "selection_empty",
                "operator": "equal",          
                "operand": true,                         
                "match_all": true 
            },
            { 
                "key": "auto_complete_visible", 
                "operator": "equal",          
                "operand": false,                        
                "match_all": true 
            },
            { 
                "key": "selector", 
                "operator": "equal", 
                "operand": "source.coffee" 
            },
            { 
                "key": "preceding_text",        
                "operator": "regex_contains", 
                "operand": "^\\s*(#)\\s*$", 
                "match_all": true 
            }
        ]
    }

Thanks, anyway.
