[PATCH] setup: Add --nowarn-if-older option

[Igor Pechtchanski <pechtcha at cs dot nyu dot edu>]

One consequence of doing releases from a separate branch, rather than the
trunk, is that self-built setup from the trunk will complain[*] that a
newer version is available (unless there was a check-in since the
release).  The attached patch adds a --nowarn-if-older (-o) option that
prevents this warning.  I'd be happy to have an alternative solution to
this problem (such as removing the warning altogether, or making it
non-modal).

Again, the ChangeLog is below.

[*] Rather annoyingly, by popping one message box per mirror, plus an
extra message box in the end.

	* state.cc (no_warn_if_older): New global variable.
	* state.h (no_warn_if_older): Declare it.
	* main.cc (NoWarnIfOlderOption): New boolean option.
	* ini.cc (do_ini_thread): Don't warn about newer setup if
	no_warn_if_older is true.
