Replace deprecated code

[jensschuppe]

• User deprecated function: Attributes passed to CRM_Core_Form::add() are not an array. in CRM_Core_Error::deprecatedWarning() (line 1053 of .../sites/all/modules/civicrm/CRM/Core/Error.php). on civicrm/import/contact/xcm - CRM_Xcm_Form_Import::buildQuickForm expects array #110

@jaapjansma is this still happening? You're currently using this more the we do...

At least here this is still an issue:

de.systopia.xcm/CRM/Xcm/Form/Import.php

Lines 42 to 48 in 0c3be7e

	$this->add(
	'File',
	'uploadFile',
	ts('Import Data File'),
	'size=30 maxlength=255',
	TRUE
	);

Should be easy enough - occurrences like these

'size=30 maxlength=255'

needs to be replaced by an appropriate array noation.
