Openemr: Remove function html_header_show() instances

[sjpadgett]

No longer used and while we're at cleaning up code wellll, why not.

[morg0n]

I can help!

[sjpadgett]

Thanks @morg0n,
Give me a day to maybe add to this. Stuff like adding dirname(__FILE__) or at min './' to requires with relative paths as needed.
Also maybe note jquery version and check back with me to determine if we can update to current version ie 3.1.1.

I got excited and did some things - I hope that wasn't terribly rude

[sjpadgett]

Not rude at all my friend. It's good for the soul to contrib to a worthy cause, is it not?

[morg0n]

Most definitely :) ~! It's the greatest Paladin playthrough!
