updated first folder according to new headline styles
updated folders preamble and introduction
static dir moved from / to source

the static dir is a temporarily dir where you put resources in
it is removed after running the scripts
by putting the static in the source dir, we can use nicer
images uri's in the rst source like:
/static/user_manual/working_with_vectors/foo.png
changing image paths not new static place
icons back (again)
update
mvoing from ../../../static to /static image uri's
translation now working :-)
