SiteConfig model: now has an all() method to return everything; useful for iterating over everything, a rare need
Mobile app: A new set of siteconfig keywords now exists to configure the color scheme, markers, etc. on the mobile-friendly version   This commit includes these new keywords in setup.php so they're configured with a new site, and full support for these configs in the mobile app. Not yet included is a way to adminster them
Mobile: on the topic of admin-specified color theming: added these default colors to the Mobile controller as static data, have setup.php load the defaults from this   Better than config.php where it won't be caught by revision control
Mobile: minor MVC fix to index.phtml, so it doesn't use Controller's siteconfig but only the template-assigned variables, as MVC intends
Mobile: added to the static $DEFAULT_LOGO the width and height, for consistency with other images
Administration panel now has a Mobile Site section, allowing the colors and markers to be customized for the mobile site
Fixes to the admin panel and mobile CSS, pertaining to the admin-specified color theme for mobile
