Adjusted zip and state field length requirements

State abbreviations, if used at all, are not neccessarily 2 characters
outside the US and zip codes aren't always 5 digits either. It's
probably a good idea not to enforce US centric length requirements to
these fields in the Location model.
Fixed code indentation for Apache virtualhost example

The code indentation was incorrect, borking the syntax highlighting in
the README.
