Summary: mplementation for PEP 318 using java-style syntax

Initial Comment:
This implements function decorators using the
Java-style syntax described in
http://mail.python.org/pipermail/python-dev/2004-June/045516.html

As the patch changes the grammar, you'll need to
make sure Include/graminit.h and Python/graminit.c
are writable after applying the patch but before
compiling (after a standard CVS checkout they are
read-only, which stops pgen from working).

Changes: 

   - adding @ as a token
   - changing the grammer for funcdef
   - adding com_decorator in compile.c
   - adding test_decorator.py (based on Guido's version)

After applying this patch, any attempts to use the
newly-built python (I deleted graminit.c and graminit.h, to
make sure they were rebuilt) gives the following on any
'import':

*-s*)  CC='gcc -pthread' LDSHARED='gcc -pthread -shared'
OPT='-DNDEBUG -g -O3 -Wall -Wstrict-prototypes' ./python -E
./setup.py -q build;; *)  CC='gcc -pthread' LDSHARED='gcc -pthread -shared'
OPT='-DNDEBUG -g -O3 -Wall -Wstrict-prototypes' ./python -E
./setup.py build;; esac
Traceback (most recent call last):

SystemError: compile_node: unexpected node type
