[RPL/2] RPL/2 4.0.9

[BERTRAND Joel]

	Hello,

	New stable release of RPL/2 with some new features, bugfixes and code 
optimization :
- new benchmark on same hardware than old one :
cauchy:[~/rpl/bench] > ./bench.rpl
+++RPL/2 (R) version 4.0.9 (samedi 23/01/2010, 18:06:08 CET)
+++Copyright (C) 1989 à 2009, 2010 BERTRAND Joël
Number of scalar operations per second and per core : 2383016

+10% of scalar operations since last benchmark.

- profiler is modified: PULPRFL does not abort on BUG() but on execution 
error.
- TRIM, REPL and TOKENIZE are added (string and list arguments).
- sockets options are now set before bind();
- shutdown() is added to all connected sockets;
- minor bug is fixed in SUB intrinsic (segfault when SUB is called with
list argument and inexistant elements).

Roadmap : terminate unformatted file support and rewrite variable 
management.

	Regards,

	JKB
