Logback as backend for ceylon.logging

[Dirk Lattermann]

Hi,

I wrote a tiny module that configures ceylon.logging to use Logback as
a logging backend (together with short instructions).

Maybe its too tiny to be worth mentioning, but you might find it useful
nontheless.

It's at https://github.com/dlkw/ceylogback

Have fun!
Dirk
