- adds routes for homepage pagination
- adds helper function to compile template file for pagination
- adds next and prev to post for next and previous page
- adds handlebars template for pagination
- 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
