credential-cache: new option to ignore sighup
Introduce new option "credentialCache.ignoreSIGHUP" which stops
git-credential-cache--daemon from quitting on SIGHUP. This is useful
when "git push" is started from Emacs, because all child
processes (including the daemon) will receive a SIGHUP when "git push"
exits.
