[PATCH v12 20/20] index-helper: indexhelper.exitafter config

[David Turner <dturner@twopensource.com>]

Add a configuration variable, indexhelper.exitafter, which provides a
default time to keep the index-helper alive.  This is useful with
indexhelper.autorun; some users will want to keep the
automatically-run index-helper alive across their lunch break and will
thus set indexhelper.exitafter to a high value.
