Add GUI shortcut for initializeWebKitLegacy

We call initializeWebKitLegacy automatically before you search all bundles just to be safe (since touching some classes before WebKit is initialized will initialize it on a thread other than the main thread), but sometimes you can encounter this crash without searching through all bundles, of course.

In this case, you can now long press on the navigation bar to call initializeWebKitLegacy
