The documentation should indicate that pres_file option for serve commande is resolved relative to cwd

[CircleCode]

Say, for example, that your are in showoff source dir.
If you run ./bin/showoff serve ./example, file example/showoff.json is not used.

One would expect that the pres_file should be found in pres_dir.

Ideally, I would request a change in the way the application works, but this would be a breaking change. So this should be stated in the documentation.

I am currently working on a major rearchitecture that will clean up a bunch of these inconsistencies
