Problems with HTTPS enabled sites

Thanks for great plugin!

However there is some issues in the WP Twitter Feeds code with HTTPS enabled sites like mine. This plugin uses protocol relative URLs (http://) which triggers alerts in certain browsers when plugin is used with HTTPS enabled site. I fixed most of the URLs manually by replacing protocol relative URLS in plugin code to relative URLS (//:), this made plugin compatible with my HTTPS enabled site. Only URL I was not able to fix quickyl was for twitter avatar image but that is not an issue for me.

Could you please consider implementing these changes in official code to make this plugin officially compatible with HTTPS?
