New community forum and donation policy

Beginning with today, our old forum on AROS-EXEC will not be available anymore. The AROS community has a new home at ae.amigalife.org and so has Icaros. The old messages are still available in read-only mode: topics which would still need answers must be re-opened on the new platform. For now, I have already set up a welcome message with few mandatory links. Icaros website has been modified accordingly: the "Community" link in the top-bar menu has been removed, and replaced by the new "Get help" section in the right side column.

I've also been informed that PayPal button for donations wasn't working anymore. Luckily, I have already been called back by a PayPal technician, and I could fix the issue. You can also give money recursively through Patreon as usual.
