Drop the section that talked about main and how to update
local checkouts - its been 2 years, people should have gotten
around to it by now. Add some general git hints instead.
Remove the mention of GNU (since that has not been case
for a long time, effectively), state that GTK is hosted
by the GNOME project, and point to GNOME as a place
for donations.
To build a better world sometimes means having to tear the old one down.

ATK served us well for nearly 20 years, but the world has changed, and
GTK has changed with it. Now ATK is mostly a hindrance towards improving
the accessibility stack:
- it maps to a very specific implementation, AT-SPI, which is Linux and
Unix specific
- it requires implementing the same functionality in three different
layers of the stack: AT-SPI, ATK, and GTK
- only GTK uses it; every other Linux and Unix toolkit and application
talks to AT-SPI directly, including assistive technologies
Sadly, we cannot incrementally port GTK to a new accessibility stack;
since ATK insulates us entirely from the underlying implementation, we
cannot replace it piecemeal. Instead, we're going to remove everything
and then incrementally build on a clean slate:
- add an "accessible" interface, implemented by GTK objects directly,
which describe the accessible role and state changes for every UI
element
- add an "assistive technology context" to proxy a native accessibility
API, and assign it to every widget
- implement the AT context depending on the platform

The README file still links to the old web page about mailing lists; the
link is now a 404 after the website redesign, and we don't use mailing
lists any more, in favour of Discourse.
