Subject: [PATCH] use travis to make releases to github

When a tag is pushed we will following this patch also do a release
build if the debug build and tests passes. We will then being packaging
for each target, along with an archive for the source code. The packages
are named after the targets.

We do a normal debug build and tests first because these are cheaper to
do and will give a shorter turnaround time for developers if any tests
fail. You can also only run tests with debug builds.

Fixes #72.
