Header image generator misreads values, creates invalid and broken XHTML

[philor]

In templates/default/functions.php:

The kubrick_header_image option is saved with an unescaped ampersand, so it breaks XHTML.

The functions kubrick_upper_color and kubrick_lower_color have a counting problem, so after saving a new set of colors they get, e.g., ee8&lo for 69aee8 and 0b7 for 4180b7. To not abandon people who have saved a set of colors with an unencoded ampersand, they need to not just take a substr starting at the right number, but actually parse the string (at least to the extent of taking the 6 characters after the first and last occurrence of "="), since the lower_color can start at either character 34 or 38.

The kubrick_head function inserts the style hidden from incredibly ancient browsers with SGML comments, so in XHTML as XML it doesn't exist.

I would like for you to attempt to use an encoded ampersand in embedded CSS. I didn't have any luck.

Ideally, it should be in a CDATA block, so unencoded ampersands would be allowed. What's browser support like here?

Mmm, nice. Easy to do if you know what you're serving, not if you don't. There is a commenting hack that apparently mostly works, except maybe in some older versions of Opera, but

<style type="text/css">
<!--/*--><![CDATA[/*><!--*/
&
/*]]>*/--></style>

is a touch ugly.

And since the colorpicker uses document.writeln(), it's also tag-soup-only. Maybe just hiding the whole thing based on html_type is the sane way out.
