[TYPO] Spreadsheet info|show|print field parameters

[jay-eleven]

Hi Ross!

I think I found a typo in the info|show|print spreadsheet field parameters:

[GamCommands.txt]

<SpreadsheetField> ::=
        developermetadata|
        namedranges|
        properties|
        sheets|
        spreadcheetid|   <------------
        spreadcheeturl   <------------

[init.py]

SPREADSHEET_FIELDS_CHOICE_MAP = {
  'developermetadata': 'developerMetadata',
  'namedranges': 'namedRanges',
  'properties': 'properties',
  'sheets': 'sheets',
  'spreadcheetid': 'spreadsheetId',      <------------
  'spreadcheeturl': 'spreadsheetUrl',    <------------
  }

I'm not sure if this is really a typo or an intended feature. I've added a pull request to fix this, feel free to ignore if this is a feature.
