travis-ci: enabling continuous integration on SDRangel

Use travis-ci as continuous integrator with builind for the following
operating systems:

- ubuntu 16.04; build with gui and without gui
- macOS 10.14, 10.13, 10.12, 10.11 with macports

This file can be used as build dependency tracker to avoid duplicated
information.

TODO:
  - windows 10

NOTE:
  - ubuntu 18.04 is not supported yet. Azure pipelines has the same
    limit.
