Give some hints about other platforms and development on the homepage

[BigMc]

Hi,

I think we should let visitors of the AGS homepage know that the games work also on other platforms. I created a Wiki page listing the ports. Would you put a link to that into the "Download AGS" box on http://www.adventuregamestudio.co.uk/AGS.aspx ? Feel free to also improve the page if I missed something. It could also be additionally linked to from the Wiki main page.

I also think a Wiki page that gives an overview over AGS development would be sensible. How to contribute, report bugs etc. I don't really know the answer to these questions myself, so anyone else willing to start this?

Alternatively, there could be a link to https://github.com/adventuregamestudio/ags stating it is the development version and on which platforms it works. There are installation instructions for the new platforms behind that link.
