Include flag to use relative paths. Absolute paths are now default.

[romefeller]

Fixing the relative path problem on macos. A new option was created --use-relative-path. Absolute paths are now defaulted.

See: #899

Usage:

ob run --use-relative-path

I have:

• Based work on latest develop branch
• Followed the contribution guide
• Looked for lint in my changes with hlint . (lint found code you did not write can be left alone)
• Run the test suite: $(nix-build -A selftest --no-out-link)
• Updated the changelog
• (Optional) Run CI tests locally: nix-build release.nix -A build.x86_64-linux --no-out-link (or x86_64-darwin on macOS)

In the future, please minimize indentation and remove any trailing white space. I find it helpful to configure my editor to highlight trailing white space in red.

Which branch of obelisk are you using? This is on develop but I'm not sure it's made it to an official release.
