[HTTPS-E Rulesets] Prevent mixed mode webogram

[Pander]

Hi all,

Webogram, an instant messenger, has troubles with Firefox's mixed mode
of HTTP and HTTPS when HTTPS Everywhere is enabled but one chooses in
the website to explicitly use HTTP-only.

Could someone look into this issue
 https://github.com/zhukov/webogram/issues/237
and see if an extra rule is needed in HTTS Everywhere in order to fix this?

At the moment, the only workaround for normal users is to disable HTTPS
Everywhere which is undesirable.

Thanks,

Pander
