Add capabillity to hijack standard browser keyboard shorcuts #84
Description
Summary
It would be useful in some scenarios to be able to override browsers' keyboard shortcuts. For example for an "on save" shortcut [CTRL+S] instead of opening native save dialog an action could be performed in TeamApps.
Current State
SessionContext.onGlobalKeyEventOccurred can already listen for keyboard events, but apparently it will still propagate them to the browser, so hijacking is not possible.
