Rename 'navigator' to 'registration'

[Marijn Kruisselbrink, 2014/10/08 23:00:32]

argh, the danger of copy-paste coding... fixed.

+    ServiceWorkerRegistrationGeofencing* supplement = static_cast<ServiceWorkerRegistrationGeofencing*>(HeapSupplement<ServiceWorkerRegistration>::from(navigator, supplementName()));

Ditto

[Marijn Kruisselbrink, 2014/10/08 23:00:32]

Done.
