[horde] Horde_Css_Parser-1.0.5 gives errors when view email

[John H. Bennett III]

Hello,

I updated my system, last night, and I'm getting this in my logs when  
looking at some emails.

Jan 12 12:22:45 mine HORDE: PHP Fatal error:  Can't inherit abstract  
function Sabberworm\CSS\Renderable::__toString() (previously declared  
abstract in Sabberworm\CSS\Value\Value) in  
/usr/share/pear/Horde/Css/Parser/vendor/sabberworm/php-css-parser/lib/Sabberworm/CSS/Value/Value.php on line  
7

Reverting back to Horde_Css_Parser-1.0.4

Fixes things.

Thank you,

John
