Force deletion of local branch, ignoring unmerged changes when cancelling a feature
Adding -F flag to 'git hf feature push' to add the --force flag to the git push command
Merge tag '1.4.2' into develop

Bugfix release
Remove unused Makefile

The install.sh script appears to be the documented install script, the Makefile
depends on git-flow which is invalid here and this only serves to confuse new
users attempting to install.
Pass args on to gitflow-installer.sh

Allow install, uninstall args to be passed through
Don't require root if install dir is writable

For many users (particularly OS X users if they've setup HomeBrew the
recommended way) the default install prefix of /usr/local/bin will already be
writable and for users specifying an alternate prefix like $HOME/bin it will be
as well.  So don't require sudo usage in such cases.
