Adding an import and export of rules to the Web.Config of IIS

These are used to redirect links pointing to specific pages of online documentation. Manual pages change names or folder names over time. The import and export should help to automate such changes.

The output should be maintainable via a simple CSV file.

Rule name, MatchUrl and RedirectUrl
Since http and https are to be supported, two rules are to be created automatically during import. For export only one.

Support of rotating backups of the web-config, also destination path and force parameter for the backup function.
