JSON configuration

Thanks to the embedded Mojo::JSON parser bootylicious configs are now much easier to read and maintain:

    {
        "base" : "/",
        "title" : "bootylicious",
        "descr" : "One-file blog engine software on Mojo steroids!",
        "author" : "vti",
        "publicdir" : "../../htdocs",
        "menu" : [
            "index", "/index.html",
            "tags", "/tags.html",
            "search", "/search.html",
            "archive", "archive.html",
            "documentation", "/articles/2009/08/documentation.html",
            "source code", "http://github.com/vti/bootylicious",
            "<b>download<em>!</em></b>", "/bootylicious.pl"
        ],
        "plugins" : [
            "gallery",
            "search"
        ],
        "footer" : "Bootylicious is powered by Mojolicious::Lite and Pod::Simple::HTML"
    }

Even though JSON RFC says nothing about comments, it is possible to use them in bootylicious configuration:

    {
        "base" : "/",
    #   "title" : "bootylicious",
        "title" : "Bootylicious"
    }
