Some Webfm Attachment GUI Improvements

When you upload an existing file, you get a "Select File Versioning Option" form. Some of our non-techie types have been confused by this. An easy way to help clarify why folks are seeing this is to add a #description to the webfm_version_form array.

Here's what my modified webfm.module webfm_version_form function looks like:

function webfm_version_form($filename) {
  $form['select'] = array(
    '#prefix' => '<div id="replace-options">',
    '#suffix' => '</div>',
    '#type' => 'radios',
    '#title' => t('Select File Versioning Option'),
    '#description' => t('A file with the same name has already been uploaded.  Please select how you want to handle with this.'),
    '#options' => array('Replace and rename original copy of '.$filename,'Replace and delete original copy of '.$filename,'Rename new copy of '.$filename,'Cancel'),
    '#required' => TRUE,
  );
