Getting grunt:build working for origin/rewrite

fixes GH-112

Issues:
-The built handlebars file wasn't getting copied to the dist directory
-CSS files get moves in theh build process, so image references were wrong
-Dynamically loaded CSS was being put into the scripts dir, which isn't
good
-No image resources were being moved during the copy phase
-The min:css and build:css html comment directive were conflicting and
leaving outo built.css.

TODO: still need to minify the css.  CSS minification is currently removed
from the gruntfile due to the issue described above.
