skin in DATA/HTDOCS (works after upgrade, works when only DATA is writable).

preference of skinfiles:
-style.css will be overwritten on every new SVN, if "DATA/SKINS/"+currentSkin+".css" exists.
-DATA/SKINS will be overwritten with defaultskins from /skins
so develop your skins in DATA/SKINS, and put them into skins for distribution.
