A few weeks ago ... the version.number changed from an integer to a
semver based string.

I guess version.number and version.version are equals now. So
version.version can be used.

This commit should fix #1735

fix passing bootstrap_args to bootstrap script (issue #1235)

update default output to reflect current packer release

Updated the spot price docs

fixed `packer --version` to show version again

Fix broken links in the DigitalOcean documentation
