Implement bump version

[jsbean]

• Update product version (Xcode build configuration)
• git tag ...
• git push origin tag ...
• carthage build --no-skip-current
• carthage archive

[jsbean]

Usage:

dn-m bump [-M | -m | -p]

• -M: Major version (1.2.4 -> 2.0)
• -m: Minor version(1.2.4 -> 1.3)
• -p: Patch version(1.2.4 -> 1.2.5)

[jsbean]

Get current version from git, then do calculation of new version based on flag.

Tags are stored as files in .git/refs/tags.

[jsbean]

Then, build an archive:

carthage build --no-skip-current
carthage archive

Then, use github-release to do something like this:

$ github-release upload \
    --user dn-m \
    --repo ${project_name} \
    --tag ${tag} \
    --name "${project_name}.framework.zip" \
    --file path/to/file
