dev-libs/v8: Version bump to 3.14.5.9 (plus backported nodejs patches)

The backported patches are necessary for dev-lang/node.
This doesn't include a fix for CVE-2013-2882
dev-lang/node: Version bump to 0.10.18

Tests run for too long for me to reasonably run them on my laptop.
Moreover, some try to bind my external interface.
