Added platform 'Atari XL'.

Don't be afraid, I'm not trying to have more retro platforms than "real" platforms ;-)
The platform 'atarixl' will replace the platform 'atari'. However I need both for some
transition period.

+Atari
+=====
+
+The platform/atari/ directory is used for targeting an Atari 8-bit computer.
+Most things are shared between the 6502-based targets so please consult
+cpu/6502/README for further details.
+
+
+The following Atari 8-bit Ethernet card is supported:
+
+- Atari 8-bit Ethernet Project: Use driver cs8900a.eth with address $D500.
+
+The 'disk' make goal requires HiassofT's dir2atr program. It is available at
+http://www.horus.com/~hias/atari/ - either as source code (being part of the
+'AtariSIO driver and utilities for Linux') or as Win32 binary program (being
+part of the 'Atari Tools for Win32').
