Delete pinch to show overlay gesture.
Don't use UrlRemap on iOS (buggy with multiple webviews)
Rework Overlay menu to be another view within the main webview.

Much more performant and less complicated this way!
Remove some dead code left from last commit
Forgot to commit iOS changes for overlay change
Quit the active app if it's deleted via HarnessServer
Merge branch 'upstream' (Delete separate overlay menu)

Conflicts:
	www/cdvah/js/AppsService.js
Delete in-app menu in favour of showing the main screen on double tap
Move webpack sources out of www/ and rename dist -> cdvah/generated
Add in missing chrome app plugins (not sure why this didn't break before)
