Convert snippets that start with http into anchor links in search result pane

[epugh]

Description

Instead of adding another key word like url or link which I discovered requires custom changes in splainer-search library, and is really built aorund the concept of just one id or title or thumb, instead we look to see if this is a URL because it starts with http. In that case, instead of using the snippet, we just grab the original value and use that to construct a clickable link.

If your snippet starts with http, like in the sentence http is the protocol of the future, then you might get a bad link....

Motivation and Context

Fixes #26

How Has This Been Tested?

Manually tested. There don't seem to be specs around this.

Screenshots or GIFs (if appropriate):

See the link is now clickable?
