Make the new web site live

[szabgab]

Let me list here what I think we need in order to turn the web new web site live.

• index.html - based on ​http://commons.wikimedia.org/wiki/File:Blue_morpho_butterfly.jpg a splash screen with a list of major features
• favicon based on the same blue butterfly
• replace the onion and double arrow icon we currently have on every page (except the index.html I gues) with a similar sized blue butterfly
• change the color and the background of the website to work well with the blue butterfly - IMHO the green won't fit but it is your call
• On the download page put instructions on how to get the new zip or msi versions for windows, improve the wording for Linux, add a few words for Mac and Source version
