Configuration file for Travis-CI

Would be nice to connect trinity project to the continuous compilation system. For example - Travis CI.
Applied patch introduce configuration file for that system and compilation finished successfully with such config -
https://travis-ci.org/ligurio/trinity/builds/13626514
If you are agree to add config to repository I propose you to change notification settings (remove "- recipients : estetus@gmail.com" and notification will be send to author, committer and owner of repository. See http://about.travis-ci.org/docs/user/notifications/) and change section with branches (I suppose to keep only master branch).
