image optimisation in comments+

I just tested GTMetrix and it shows bad optimisation for comments+ as it does not use image sprites for the social media icons.

Can this be added to be fixed for the next update with your dev team?

See below:

The following images served from <domain> should be combined into as few images as possible using CSS sprites.
