RTL support – quick fix

It will be great if you include the css for rtl support, it is really simple, it will save me (and surly others) the manual addition of these lines on any site they use your plugin:

[dir="rtl"] #gp-social-share li:first-child {
	margin-right: 0;
} 
[dir="rtl"] #gp-social-share li:last-child { 
	margin-right: 10px;
}
