Incrementing per commit

When using the continuous deployment mode (which will increment the SemVer every commit) all builds must have a pre-release tag, except for builds which are explicitly tagged as stable.

Then the build metadata (which is the commit count) is promoted to the pre-release tag. Applying those rules the above commit graph would produce:

e137e9		->		1.0.0+0
a5f6c5		->		1.0.1-ci.1
adb29a		->		1.0.1-feature-foo.1 (PR #5 Version: `1.0.1-PullRequest.5+2`)
7c2438		->		1.0.1-feature-foo.2 (PR #5 Version: `1.0.1-PullRequest.5+3`)
5f413b		->		1.0.1-ci.4
d6155b		->		2.0.0-rc.1+4 (Before and after tag)
d53ab6		->		2.0.0-rc.2 (If there was another commit on the release branch it would be 2.0.0-rc.3)
b5d142		->		2.0.0-ci.0 (2.0.0 branch was merged, so master is now at 2.0.0)

As you can see the versions now no longer conflict. When you want to create a stable 2.0.0 release you simply git tag 2.0.0 then build the tag and it will produce a stable 2.0.0 package.

For more information/background on why we have come to this conclusion read Xavier Decoster's blog post on the subject.
