manually added normalize

bower did not add normalize link in my <head> again, and I don’t know
why bower isn’t working that way for me. But, now, under app, after
using the “bower install normalize.ss —save”, there is a NEW “bower
components” folder containing the normalize folder generated by bower.
I think I will copy and paste that folder in the old “bower components”
to be safe. But I do not understand why this happens.
