Catch navigation before it happens

[wvengen]

Several workarounds were needed to cancel navigating to a link that is supposed to load in the system web browser. Something like the CB-14188 PR would allow inspecting the URL and cancel loading the external page before it happens. This would allow removing quite some code, be less error-prone, and provide a better experience.

Finish the PR and integrate it. Work has already started on branch feature/beforeload.

Done in 08cdf40. When a new version of InAppBrowser is released (3.0.0+), use that plugin from npm.

Verified on iOS.
Discovered an issue on Android where the first time an external link is clicked, the beforeload event does not seem to be caught. Subsequent times work fine.

Thanks for your message, I hope to be able to look into this again at some point.
