Rewrite the way git-flow initialized its variables in git-flow and assumed
existence of a valid git repo. Instead, functions gitflow_load_settings()
and gitflow_require_git_repo() have been added that can be called in each
submodule that requires such.
Specifically, git-flow init does NOT use this.
