Automatically add HTTP schema to URL when it is missing

Is your feature request related to a problem? Please describe. I copied the URL 192.168.3.8:9227 I used with curl into the dejavu connect URL box and wondered why it did not work. It turned out that dejavu requires the http:// schema.

Describe the solution you'd like dejavu should automatically prepend the http:// schema to the URL if it has no schema.
