Adding git-ignore command, tests, and documentation.

git-ignore will allow users to quickly add entries to the gitignore files in the repositories.

Many times, I'll have a config file or log file buried in a series of sub-directories and find it frustrating to edit the right git ignore with the right relative path to the file that i want to add. This script makes adding items to a gitignore file easier.

Instead of managing paths and relative paths such as echo "path/to/the/file.txt" >../../../../../../.gitignore git ignore path/to/the/file.txt No matter what directory that is in, the correct relative path will be added to the gitignore.

This script will also give the ability to add directories, extention globs, and files to any gitignore in parent directories. Furthermore, it allows you to easily open the gitignore file in your favorite editor from anywhere
using: git ignore --edit

I have been using this script for years and it has made things much easier for me, so I figured I'd contribute.
