Friendly names for config parameters

[cgarwood]

Module's should have an object for each config parameter that includes a friendly name, type, and possibly validation rules.

For example:

module.config = {
  "name": {
    "name": "Instance Name",
    "type": "string"
  },
  "host": {
    "name": "Hostname or IP Address",
    "type": "string"
  },
  "port": {
    "name": "Port",
    "type": "number",
  }.
  "version": {
    "name": "Software Version",
    "type": "select",
    "options": {
      "6": "v6",
      "7": "v7.8.9 or higher"
    },
  },
  "use_ssl": {
    "name": "Use secure connection",
    "type": "boolean"
  }
}
