Bug#817939: RM: fw4spl -- RoQA; RC buggy, NPOASR, depends on to-be-removed package

[Esa Peuha]

Package: ftp.debian.org

fw4spl has had only three upload to Debian: the first two a few
days apart in March 2015, the third in July. It has never been in
a stable release, and not likely to be because it has two RC bugs
(#797475 and #797481) and at least one bug that is going to
become RC (#809935). fw4spl is also one of the packages blocking
the removal of insighttoolkit, so please remove it.
