Add an option to import the svn:ignore properties to the Git cloned repository

[Silvestre Martins]

This can be done easily manually but at least this should be included in the tutorial on https://bitbucket.org/atlassian/svn-migration-scripts/overview

git svn show-ignore > [destination]

It should also be stated what is the preferred way of handling the ignored files: using a global configuration .gitignore file or store the list of ignored files directly under .git/info/exclude directory.
