Custom CAs not supported?

[lewellyn]

When visiting a page secured with a certificate issued by an internal CA, or a self-signed certificate which is a special case of a private CA, Liri provides a grey screen and no way to continue to the site or to import the CA certificate. This makes using Liri in an Intranet setting more challenging than the annoyance of not supporting unqualified hostnames (#53 and #205). This may be somehow related to #129 if Liri simply can't or won't show security-related dialogs yet.

It appears to not use the OS X trusted certificate store. I assume this is the case on other platforms as well, though I cannot readily check.
