[Chilli] CoovaChilli monitoring strategy

[David Bird]

Upgrade. There were a couple "crashing" bugs in older 1.2.x versions.
Also, the compile time option --enable-chilliredir will no longer
automatically mean the chilli_redir process is forked off... you now
have to also use --redir at runtime. So, it's safe to compile with
--enable-chilliredir and you can make the --redir decision at runtime.
