Instead of betas, which I think are more useful for manual 
testing before a release, I'd recommend to set up a dimension / a 
cron with nightly builds.
Github CI and the install script support them (hence so does 
travis-ci), by using `dmd-master` / `ldc-master` and 
`ldc-latest-ci` / `dmd-nightly`, respectively.
