Change path to stylesheet in p01-contact/src/P01contact.php, or make it configurable?

[ohnonot]

I'm refering to this line.
On my machine it returns an invalid path (404) because both my server root and the plugin folder are symlinked.

Could this be made user configurable?
I have an implementation in the works in my fork but did not want to mess with this file because I don't know how GetSimple works.

I could imagine something like this:

if (empty($this->ContactStyle)) $this->ContactStyle=SERVER.RELPATH."style.css";
$defaultStyle = '<link rel="stylesheet" href="'.$this->ContactStyle.'"/>';
