Title: Fixing mimetype generation on Mac OS X

In Mac OS X, Make defaults to /bin/sh, where `echo` doesn't understand the `-n` parameter (so the mimetype is set as "-n application/epub+zip").

This adds a check for the condition where `-n` isn't supported by default and forces bash as the `SHELL` if that is the case.
