Add configuration options to allow HTTP and download images from local network

[HCl-not-HCi]

Hi, I added two new configuration options to the plugin because I needed to download images from a CMS that is located on a host in the local network (whithout using HTTPS). In the current version of the plugin, URLs that contain a private IP address or the hostname "localhost" are ignored, i.e. images are not downloaded. Also, all URLs are rewritten from "http://example.com" to "https://example.com".

So I added these new options:

Property	Type	Required	Default	Description
forceHttps	Boolean	No	true	Enable/disable rewrite from http to https
downloadFromLocalNetwork	Boolean	No	false	Download images from local network (e.g. private ip address or localhost)

The default values are chosen in a way so that the behaviour of the plugin stays the same as before if the options are omitted.

I think other people may run into the same problem, so I created this PR.
