Release/2.2.0 (#75)

* docs(changelog): add release notes

* feat(git-flow): add support for busybox(#12)

* feat(init): add support for environment credentials (#19)

Allows git flow to fall back to the same environment variables git uses
for setting the author and committer details if they are not present in
the users .gitconfig

* feat(init): add option to sign initial commit (#59)

When running git flow init the following option is now available when
creating a git repository using git flow..

1) -g, --[no]sign	Sign initial commit when creating a repository

When setting up git flow in a freshly created git repository with no
prior commits or when using git flow to create a git repository in an
existing folder the sign flag will create a signed empty commit with the
message initial commit.

* feat(feature): add feature release command (#64)

Added git flow feature release to provide a quick way to create a
release branch from a existing feature branch.

* fix(hotfix): git flow hotfix track fails due to branch name check (#68)
* feat(hotfix): add cherrypick option to hotfix finish (#73)
* feat(hotfix): add  backmerge option to release branch (#71)
* fix(hotfix): git flow hotfix finish -b back-merges to develop (#66)

When runing hotfix finish the following options have been the following
options have been added:

1) -r, --releaseBackmerge	Back-merge to release branch if exists
2) -c, --cherrypick		Cherry Pick to develop instead of merge
3) -b, --[no]nobackmerge	Don't merge master, or tag onto develop

NOTE: One one of the above three options can be used at any given time
since it doesn't make sence to combine them.

* fix(log): fix git flow log help message (#15)

git flow log help no longer implies it can only be used with feature
branches

* chore(release): release version 2.2.0
