- ghost.js - globals/globalConfig has become settings / settingsCache to make it clearer
- app.js - the ghostGlobals local cache is gone, and the use of res.locals has been cleaned up and simplified, although this needs to be properly split into frontend and admin locals (to be finished in #124)
- frontend/index.js - doesn't need to be passed globals and nav properties as res.locals does this for us
This implements #106.
* Added require-tree which is based off of @ricardobeat's module. Fully async.
* I've moved active theme and active directory to settings from config as well.
* Modified settings.hbs and settings.js to display the raw json under Settings/Appearance
