Stop using Werror and Wall

[dpryan79]

Paragraph is currently not compilable because both it and the vendored graph-tools use -Werror -Wall. Patching the main paragraph CMakeLists.txt still yields:

That's since the vendored graph-tools also has this. Please just remove these, you can't possibly hope to keep up with every compiler out there.
