Idea: Build project on Travis-CI

[russplaysguitar]

I just got the source, ran the tests, and whoops: there are a few failing tests. Since I'm new to the project, I have no idea how long these tests have been failing.

It would be helpful if gladius-core was built via Travis-CI (or something) so that I could check my results against the build server.

I recently put an npm-based project on Travis-CI, so it should be possible for gladius-core, too (I think).

I'd like to be assigned to this issue, I just want to make sure the project maintainer(s) think it is worthwhile before I try.
