[dev] Fix: Colorpicker javascript error

[Cariad Ilmàra]

Hello,

Here's a fix I made for the colorpicker (horde/util/colorpicker.php) to
avoid javascript errors (colours with negative values) with IE.

Triple checked it; and it seems as precise as the old one to me...

Sorry for the other email... I screwed up between the lists... :(
