Now compliant with HTTP/1.1 RFC7230, so that it can be externally retrieved with nodejs and axios (#538)

Browse Source 
Makes this page compliant with HTTP/1.1 RFC2616 and RFC7230

"HTTP/1.1 defines the sequence CR LF as the end-of-line marker for all protocol elements except the entity-body"

This only had LF, and when used with nodejs and axios that page would fail to be retrieved and throw a HPE_INVALID_HEADER_TOKEN error. (other pages likely need that fix, but retrieving the image was most important and most useful, I personally use it with Scrypted, which then uses this as the camera snapshot in Apple Home app)

Added -n to echo to make it clearer for myself, which removes the otherwise automatically added LF
