feat: add aliases to all commands

GitFlow now supports aliases!

Who has time to type out the full command anymore?

- Type in at least three letters of the command and you’re good to go.
Misspell the entire rest of the word, it doesn’t matter.
- Use single letters for common commands.
- Use alternate terminology (e.g. ‘hotfix’, ‘docs’, ‘initialize’)
feat: add symlink to gitflow alias - gfl

Create a new alias for the `gitflow` command itself. Use `gfl` if
you’re too lazy to write out ‘gitflow’.
