Create new images for biojs.net main page

[jayjayjpg]

As discussed a couple of new images for the BioJS homepage would be necessary for our header and benefits section. Recent image ideas:

• close-up of a laptop with different BioJS components on screen
• people discussing in front of laptop
• presentation in seminar room with BioJS visualizations on screen

I think that can closed - we only managed to check one of the three list items off the list of image suggestions, but it seems to be good enough :)
