auto whitespace cleanup
removed global rendr.entryPath

in favor of passing entryPath as a server option.

modelUtils is now an object on App instead of a requireable util.

The viewEngine caches layouts based on entryPath.
Pass entryPath as a server option in the example instead of global rendr.entryPath
Version bump

Need rendr-handlebars to point to the new version of rendr
allow modelUtils to be passed in from the server to the server app instance.

This allows for the author to modify modelUtils at runtime.
