Several modifications to work with latest Backbone.

- Updated README to be more obvious about NPM install.
- Changed to use Lo-Dash instead of compatibility build.
- Removed dependence on `View#options` which was removed in Backbone
  1.1.0.
- Removed unused loader setting from client config.
- Broke out main into a separate define to use CJS syntax.
- Cleaned up the application router to not be so redundant.
