[TYPO3] make title and alttext required

[Ralf Hettinger]

Whoops,

this introduces a syntax error... better use

'altText' => Array (
  'exclude' => 1,
  'label' => 'LLL:EXT:cms/locallang_ttc.php:image_altText',
  'config' => Array (
    'type' => 'text',
    'cols' => '30',
    'rows' => '3',
    'eval' => 'required'
  )
),
'titleText' => Array (
  'exclude' => 1,
  'label' => 'LLL:EXT:cms/locallang_ttc.php:image_titleText',
  'config' => Array (
    'type' => 'text',
    'cols' => '30',
    'rows' => '3',
    'eval' => 'required'
  )
),
