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.
Documented include/reddav.php a bit more to understand what it is
about to try to clean up some parts. Still a lot to be done here.
I put serveral @todo markers that need to be checked.
Moved some more HTML to template file.
Changed getETag() return format according to documentation. (ETag MUST
be surrounded by double-quotes)
