adding of .generic-content-wrapper is needed and useful for derivative themes but it should not contain any styling information for redbasic theme. therefor i added .generic-content-wrapper-styled as a quickfix for spots where redbasic is not finished yet.
Sidenote: please avoid opening a div in one *.tpl and close it in another or (even worse) open a div in a *.tpl and close it in an already templatified mod/*.php. This will really make the code and templates very, very confusing.
Moved HTML for the directory listing from include/reddav.php to it's
own template file.
Still need to clean it up bit more, but should be useable already.
