BriskBard, CEF4Delphi, WebView4Delphi, WebUI4Delphi and WebUI4CSharp

Hi,

I uploaded a new version of CEF4Delphi with these changes :

• Faster browser destruction. All timers have been removed from the demos.
• Removed unnecessary client handler class in TChromium. Now there's only an interface.
• Fixed an old memory leak in popup windows.
• Added a new function in TChromium to set a new parent window for the browser : TChromium.SetNewBrowserParent

OSR popup windows still need to use a timer but all other browsers can be destroyed without them. Read the comments in the source of MDIBrowser or ToolBoxBrowser for the details.
