Code Issues Proposed changes

Hide hasFlash inside of UserAgent.Flash.isInstalled

Browse Source 
Clarify this only means the Flash plugin is installed in the browser.
It may be disabled by the user's preferences, or set to "click to run"
mode, where an empty gray box is displayed until the user clicks the
box to start the Flash content.
