Subject: [PATCH] set up multi-os testing in travis

Requires beta access, thankfully the travis gods have blessed us for the
main repo and my fork!

This should allow us to make sure scm_breeze operates reliably in both
Linux and BSD/Darwin, because there are small shell differences
(especially with default tools) that are causing errors I noticed on
MacOSX.
