jQuery2 update, Custom Icons per dial, Bookmark Folder editing and Completed Icon font usage

Hello again :) I've been just doing a bunch of house-cleaning like unifying quote usage and spaces etc.. 
Hopefully you'll see that everything is in working order and you like the result!

At the end of the day it is ~60% smaller overall, and the speed dial page loads/displays ~30 milliseconds faster :)

This is the result of my work and how my dial looks.

Note: if you added "file://*/*" to the permission entry in manifest.json, you could use images on-disk for the custom thumbnails. But that would be your call if you'd like to change it.
