Dry run option

Merge pull request #48 from phish108/master

Adding DRY_RUN feature that fixes #47

Retrieve latest semvar tag in order

• Use the git for-each-ref command to extract the last semver tag in order, and only if it actually looks like a semver.
• If semver fails at generating a new tag, don't just add v or $pre_release to an empty string.

Custom tag option

Merge pull request #29 from imdanielsp/master

Add an Explicit Example of Optional Env Var

Create pre-release tags for Pull Requests

This lets the user define that only the master branch should be tagged.

Other branches or pull requests will compute a new version number (bumped as usual). But the version will be marked as a pre-release thanks to the pre-release postfix. So, instead of computing 1.2.3, the script will compute 1.2.3-1a2b3c4 and the next revision of the Pull Request (or feature branch build) will compute a similar version 1.2.3-2b3c4d5 (since no tag was put and supposedly master did not evolve in the meantime).

Set Action Output

• Sets the new tag as an action output of new_tag

Script improvements

• Tag version with v character (optional)
• Dynamically get repo name, remove need for manual config of REPO_OWNER
• Get refs api URL from event payload

Skip version bump if commit already tagged

• Skips if commit is already tagged (#11)
• Adds customizable DEFAULT_BUMP config, defaults to minor.

1.4.0 Use Alpine docker image to reduce Action runtime.

• Use prontotools/alpine-git-curl docker image
  ** Runtime from ~1m 30s to ~48s
