powerpress_subscribe shortcode display issue

Hello

Fantastic plugin by the way !

In the latest version, there is a small css issue with the way the powerpress_subscribe shortcode display the title:

The title is displayed over the Subscribe to overline.

The css that cause problem is in /css/subscribe.css, line 30:

.pp-sub-widget div.pp-sub-t {
	font-weight: bold;
	margin: -15px 10px 0 10px;
	padding: 0;
	font-size: 200%;
	color: rgb(0, 51, 102);
}

The negative top margin is the cause.

The fix is easy: use the previous working css:
margin: 10px 10px 0 10px;

Thank you in advance.

Have a nice day!
