Sidebar update

• [x] Remove white background in the main Search/Replace tab so that the sidebar stands out more
• [x] Use the SVG logo from the site but include the file in the plugin
• [x] In WP Migrate DB Pro's sidebar the text in the top banner is an image. I'd like all the text in this sidebar to be text so that it matches the WordPress font.
• [x] The whole "Upgrade to Pro" black block should be linked to https://bettersearchreplace.com/?utm_source=insideplugin&utm_medium=web&utm_content=sidebar&utm_campaign=pro-upsell
• [x] Use WordPress dashicons for the check marks and the stars
• [x] Don't use Gravatar for the reviewer's avatar. Copy the avatar image file into the plugin.
• [x] Link "@philraymond via WordPress.org" to the actual review

I've copied the HTML below from WP Migrate DB Pro and adjusted the campaigns[] and source hidden inputs. Feel free to tweak the rest as needed.

<form method="post" action="https://deliciousbrains.com/email-subscribe/" target="_blank" class="subscribe block">
    <h2><?php _e( 'Get 20% Off!', 'wp-migrate-db' ); ?></h2>

    <?php $user = wp_get_current_user(); ?>

    <p class="interesting">
        <?php echo wptexturize( __( "Submit your name and email and we'll send you a coupon for 20% off your upgrade to the pro version.", 'wp-migrate-db' ) ); ?>
    </p>

    <div class="field">
        <input type="email" name="email" value="<?php echo esc_attr( $user->user_email ); ?>" placeholder="<?php _e( 'Your Email', 'wp-migrate-db' ); ?>"/>
    </div>

    <div class="field">
        <input type="text" name="first_name" value="<?php echo esc_attr( trim( $user->first_name ) ); ?>" placeholder="<?php _e( 'First Name', 'wp-migrate-db' ); ?>"/>
    </div>

    <div class="field">
        <input type="text" name="last_name" value="<?php echo esc_attr( trim( $user->last_name ) ); ?>" placeholder="<?php _e( 'Last Name', 'wp-migrate-db' ); ?>"/>
    </div>

    <input type="hidden" name="campaigns[]" value="9" />
    <input type="hidden" name="source" value="10" />

    <div class="field submit-button">
        <input type="submit" class="button" value="<?php _e( 'Send me the coupon', 'wp-migrate-db' ); ?>"/>
    </div>

    <p class="promise">
        <?php _e( 'We promise we will not use your email for anything else and you can unsubscribe with 1-click anytime.', 'wp-migrate-db' ); ?>
    </p>
</form>
