tk-brief not working because package koma-script changed

[Stefan]

tk-brief tries to load scrlettr.cls, but this changed to scrlttr2.cls.
Need to change this at least in /usr/bin/tk-brief.
I think this problem exists since trusty.

1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu
Description: Ubuntu 15.10
Release: 15.10
2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center
tk-brief:
  Installiert: 5.9-1.1ubuntu1
  Installationskandidat: 5.9-1.1ubuntu1
  Versionstabelle:
 *** 5.9-1.1ubuntu1 0
        500 http://de.archive.ubuntu.com/ubuntu/ wily/universe amd64 Packages
        100 /var/lib/dpkg/status
3) What you expected to happen
tk-brief working
4) What happened instead
error message: scrlettr.cls not found

I think, the interface changed from scrlettr to srclttr2, so there is more work to do.
