cleanup/streamline/improve automated checks:

 - use a single .travis-ci.yml for all check types (syntax on whole file, syntax on diff/PR, full syntax + URL checks)
 - only check full file syntax on pushes to master
 - only check diff on pushes to branches/PRs
 - setup a weekly cron job on https://travis-ci.org/github/awesome-selfhosted/awesome-selfhosted/settings to run thee full test suite
 - define all tests in Makefile, let .travis-ci.yml hanlde travis-specific logic only
 - rename and document makefile targets
 - remove obselete.duplicate bash syntax checks
 - check github last commit dates on github.com repositories during full checks
 - simplify/cleanup 'make add' target
