Improve image helpers for new configurations
Default bower directory to bower_components
Remove rails example
Remove extra generator output for now

we can do this effectively. Need to look at Thor's formatting options,
   and maybe steal some ideas from Yeoman.

This reverts commit 2f0ccfa0201a6ded7dfa44cb7c8ac902f8ef7030.
Include jquery-ujs for bower by default
Include default build/server tasks
Update paths to scripts and styles
