simple URI rewrite rules config for webserver

we have a test which required traditionally lighttpd to be executed
as it requires a webserver supporting some kind of URI rewriting.
Now with some lines of code our own webserver can do this and the
testcase can be enabled by default. This test hinted at the bug fixed
in the previous commit, so having more tests which can easily be run
is a good thing.
