Quick fix for WinForms WebView being broken

At the least navigate to a page on startup. Still all navigation buttons are broken like already recorded in #241 and what it points to.
Update WebView.cs

Duh
Added Cut method to ManagedCefBrowserAdapter
Added shortcut to CefSharp.Wpf.WebView (also changed from if else branch to switch)
Add modifiers param to SendKeyEvent
Sent through key modifier so things like Shift-LeftArrow as expected
Also include Home key in list that gets sent to the browser directly

WPF ZoomIn/Out Functionality
Added missing space + reformatted to fit into the "132 columns" rule. (will add that to the contribution guidelines)
Removed the comment from here altogether. It's better to keep it DRY and only have the text in one place (that is, in the interface in this case).
