getting some dm gems on travis

[cldwalker]

Hi All,
I've been using dm for more projects and would love to see it on
travis so I know it tests well across rbx, jruby and mri. Would you
all take pull requests to add travis to dm-core, dm-migrations, dm-
timestamps and dm-validations?

Thanks,
Gabriel

P.S. I maintain 20+ gems and can attest to travis being useful for
monitoring support across rubies

Hey,

I've tried running dm-core specs on travis and it turned out the suite is too big and we need a separate worker. Rest of the gems will run fine but for now our current CI is all we need. I'm pretty sure DM2 specs will be all on travis though, for example all veritas gems and virtus are on travis: http://travis-ci.org/#!/dkubb/veritas or http://travis-ci.org/#!/solnic/virtus.

Cheers
