add dep on concurrent-output, and re-enable -O0
Using the external concurrent-output library lets it be built with -O2 as is needed to get good runtime memory use. Enabling -O0 because ghc is using rather a lot more time and memory due to the new more complex types. old master branch: Linking dist/build/propellor-config/propellor-config ... 24.59user 0.97system 0:25.93elapsed 98%CPU (0avgtext+0avgdata 354612maxresident)k 1544inputs+46064outputs (0major+371244minor)pagefaults 0swaps this branch before -O0: Linking dist/build/propellor-config/propellor-config ... 25.56user 0.73system 0:26.61elapsed 98%CPU (0avgtext+0avgdata 345348maxresident)k 0inputs+43480outputs (0major+364163minor)pagefaults 0swaps this branch with -O0: Linking dist/build/propellor-config/propellor-config ... 11.91user 0.75system 0:12.97elapsed 97%CPU (0avgtext+0avgdata 237472maxresident)k 16inputs+37264outputs (0major+336166minor)pagefaults 0swaps Above benchmarks are building all source files needed by config-simple.hs. The story is rather worse for joeyconfig.hs; building it now needs over 500 mb even with -O0 :-/

-O0 is better because ghc takes less memory to build propellor.
