Includes formatting/styling changes to clarify the data being presented as well as align styling with middlemanapp.com. Also adds features and fixes to the sitemap view to show ignored files differently, hide redundant information, print data/options as a hash instead of as array pairs, and to list out available locals defined on a page.
This is another metadata page that uses the new configuration system to
show all the available options, their current values, and their defaults.
This is still unstyled, but the info is there. I still need to add on a
method for extensions to register their configuration with the global
config so they show up (stuff like blog) but this is a start.
