fix example

- use parent directory for locator-handlebars
- use expyui.debug() over deprecated app.yui.debugMode()
- add missing .extend() after expyui api update
- update devDeps (use parent node_modules)
rm debug, use npm dependency for locator-handlebars
put "yui" back as an explicit dependency
