[Plugin: Cimy Extra User Fields] Stylesheet not loaded when using https (blocked

After I converted the admin side of my site to default to https, I noticed when checking for problems that https://ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/themes/smoothness/jquery-ui.css was being blocked from loading because of “mixed content”.
I found that module cimy_uef_init.php (in version 2.6.3) had that URI hard coded to use http, regardless whether the site is being loaded with http or https.
I changed cimy_uef_init.php to use a protocol-neutral URI, //ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/themes/smoothness/jquery-ui.css, instead – and that fixed the problem.
