List of available packages

Until now, the only way of knowing what packages were available on the yun was to issue

opkg update
opkg list

Since today, we are going to publish the list on the download site. The list is available here: http://downloads.arduino.cc/openwrtyun/1/packages/index.html

(yes, we used to have that list already, but the new storage does not support file listing so we had to generate it on our own)
