Patching Duckling

[jneira]

• I had to mark unbuildable the components
  • duckling-regen-exe: needed to generate the haskell files (i think): it uses haskell-src-exts and reach the class size limit
  • duckling-example-exe: it uses snap-core
• I've not tested it at runtime

Fixes #143

Thanks for all the patches, @jneira!

Hi @jneira - please forgive my ignorance, but is snap-core inherently incompatible with 'eta' or would it require its own patch? We are hoping to use duckling-example-exe in our application.

I got 'duckling-test' to build successfully

but does not pass the unit tests:

No worries! snap could be patched for eta (like warp/wai) but maybe it could be quite work. However i will give a try to confirm it.
I'll take a look to test suite errors, i hope it can be fixed without too much problems.
