(a need for OOo package)
update test

fix: handle the case the previous file used to be a directory separately, baselayout failed without this

* fix: correctly use build no in determining which packages may be upgraded as in api.list_upgradable. there was a really foolish code segment there :(

* there was a db fix, let's make sure

* less frightening message for normal errors

script

* fix: do not remove package from component if we are not removing a package from repository! this is a workaround. the design of packagedb somehow does not look very good :/
