Add vimeo to blocksocial

I've added vimeo to my site, but every update to the module i need to add it again and again, so i thought it might be better to add it to the original module, only this is the first time i do this i don't really know how. I need to add code also on the global.css that how  i did it to add the vimeo icon, and also in the theme blocksocial.tpl:
