added hover state to images and transitioning svg image, new fonts

Hey Kristen, 

For some reason the svg image is still not positioned properly on my screen even after I got the most updated version (I checked this with the old and new file, so I know I definitely had the newest version you and Asaf were working on). As long as it looks good on your screen I suppose because you and Asaf were both able to see it properly. 

The changes I made were:
1. Adding new fonts
2. Adding a hover state on the images which just changes their opacity
3. made the svg image transition with colours!
4. changed the background


Feel free to change any of this. I will spend the rest of the evening brushing up on javascript and jquery and then tomorrow I will probably try to work on it at some stage again:)
