Add InAppBrowser plugin
Dynamically replace links with window.open scripts for ext. browser

This function adds a dom-modification observer, and each time the
dom changes it finds all anchor tags, finds their target, and replaces
them with an on-click even that calls window.open.

window.open is routed through the InAppBrowser plugin, and that opens
them in the system's browser.
