Small tweaks

On the spell-index-page "Spells Light" i added some icons so it's easier to see that you can expand the rows to see the spells description. You can click on the right side of the name all the way past the Level column.

You are now able to add and remove spells from the list to the active spellbook. But right graphics will not at this moment change. So the button will still be green or red until you reload the page. The buttons will not update when activate another spellbook from the navigation.
But.. the buttons will work, so if the spell isn't present in the active book it will be added and vice versa. Im trying to find the time to finish this feature, but I need some beta-testing in a live version to accomplish that.

Facebook login / integration is on it's way.
