Detect .html resources and update "Download" to "View Page"

Update "Download" button to "View Page / Visit Site / ect" for external resources that lead to valid URLs.

For example, an external resource is entered into WPFD with the following:

Title: Zapier API Documentation
Type: External Resources
URL: https://zapier.com/learn/apis/

When displayed on the site, the button says "Download". When clicked, the user is expecting to download something... not be taken to another website.

Something along the lines of this would be added to the tpl.php :

<?php if ((int) WpfdBase::loadValue($this->params, 'showdownload', 1) === 1) : ?>
    <?php
    $bg_download = WpfdBase::loadValue($this->params, 'bgdownloadlink', '');
    $color_download = WpfdBase::loadValue(
        $this->params,
        'colordownloadlink',
        ''
    );
    $download_style = '';
    if ($bg_download !== '') {
        $download_style .= 'background-color:' . $bg_download . ';';
    }
    if ($color_download !== '') {
        $download_style .= 'color:' . $color_download . ';';
    }
    ?>
    <!-- DETECT FORMAT -->
    $format = '';
    if ($format == 'html') {
        $format .= 'Open Page';';
    } else {
    	$format .= 'Download';';
	}
    <a class="downloadlink wpfd_downloadlink"
       href="/<?php echo esc_url($file->linkdownload) ?>" style="<?php echo esc_html($download_style); ?>">
       	<!-- BUTTON TEXT DEPENDENT ON FORMAT -->
        <?php esc_html_e('$format', 'wpfd'); ?>
        <i class="zmdi zmdi-cloud-download wpfd-download"></i>
    </a>
<?php endif; ?>
