Update instructions for setting version number

Need to take account of test_with_tycho.patch
Manually fix up runalltests version numbers
Merge remote-tracking branch 'origin/development' into travis_ci_fix_runalltests_version_number
Don't error on upload if S3 is not available

We need this to work so that builds run without secure variables do
not fail (e.g. Pull Requests)
Update TestDependent.travis for fabioz
Merge pull request #84 from jonahkichwacoders/travis_ci_fix_runalltests_version_number

A few Travis CI/Tycho updates
