Adjust priorities

User name truncation

By default, all usernames will truncate at the '@' character. This can be configured differently if desired. I did some refactoring of regex parsing to move it out of the config class and into it's own class.

Adjust config merge

When the override config has an appSettings/add element that the base config does not have, the base config will copy over the override config element.

Before this commit, the override appSettings/add element would be ignored if the base config did not also have the same element.

Handle hyphens

Windows firewall will use a hyphen if the range is not a proper cidr mask
