Adding windows install intruction for libintl3.dll

I found I also needed to install this file. It was mentioned in
issue #109. Adding this step to the instruction might help others
avoid this same problem.

Install script depends on Bash-only features, needs slight adjustment!

current branch, if any.

This fixes #127.

Thanks for the MSysGit installer!

Installer for the Windows msysgit environment

Set GITFLOW_DIR correctly if git-flow is a symbolic link

Thanks Kiall for the Debian package files!

Add debian/ubuntu packaging

Fixing some minor mistakes in debian/control metadata - followup to ca475abb

This allows a user to create a symbolic link to git-flow in their
personal bin directory (e.g. ~/bin) without having to add the source
tree to their $PATH or do a system install.

- Added fetching develop branch from origin when fetch flag is on in feature finish

Fixed require_tag_absent to not break when the list of tags contains an ambiguous entry, e.g. looking for "1.0.1" in "0.1.0 0.1.1 0.1.2 1.0".

This installer:
- detects the Git installation path
- checks prereqs (git, getopt.exe)
- delete old gitflow install
- install gitflow files

"Access denied" errors are detected and the user is given advice in that case (
use full administrator rights).

Using --recursive simplifies instructions related to the submodule
initialization for shFlags.

Thanks Joseph! I've added you to the AUTHORS file, too.
