fixed syntax of example to please rake check:syntax :)
find libyui in a prefix outside /usr

and let the sources use the yui/ directory part consistently:
swig/yui.i used #include "yui/foo" but %include foo
install the scripting languages libraries under our prefix

it will not actually work, but "make install" passes as non-root then
which matters for the CI build script
version + changelog
Merge branch 'use-libyui-rakefile'
