Wrong path resolution for skin files

[stat1x]

Hi,

In RichTextElement class the skinFilename and skinDirectory are wrongly set. If your typo3 installation is in a subdirectory the paths are wrong so the cache files are empty.

I fixed it by setting the path manually like this :

 // Get skin file name
$skinFilename = '/typo3conf/ext/rtehtmlarea/Resources/Public/Css/Skin/htmlarea.css';
$skinDirectory = '/typo3conf/ext/rtehtmlarea/Resources/Public/Css/Skin';
