Subject: [PATCH] Remove commit-log-editor's dependency on
 Module::Load::Conditional

This module isn't available in Perl 5.8.8 (the version used on Leopard).

Fixes <http://webkit.org/b/64198> REGRESSION (r90583):
webkitpy.common.checkout.checkout_unittest failing on Leopard

Reviewed by Daniel Bates.

* Scripts/commit-log-editor: Use the new loadTermReadKey() function instead of
Module::Load::Conditional::can_load.
(loadTermReadKey): Added. Tries to load Term::ReadKey and returns true if it's successful.
