added heads-up for Polymer/polymer#677 

as there was (pedanticly spoken) a noscript attribute missing, I did add the script tag to hint to the workaround to Polymer/polymer#677

display:block breaks elements that use display:flex box
Clarify the need to update `bower.json`

If the names in `bower.json` are not updated to the new element, the `gp.sh` script will build broken links still pointing to `seed-element`.

Perhaps this will save others from some confusion.
