Terminal: Bug 434939 - Keybinding conflicts when installing into JEE

The "Alt+V" key binding reported an error when installed into the
Eclipse JEE package. This is resolved by making our TerminalContext
a child of the Eclipse Window context.

At the same time, provide better human-readable labels for the Terminal
Edit Context (menu on Terminal Widget) and Terminal Typing Context.
And, register more Alt+Char key bindings after carefully reviewing
existing Eclipse Main Menus, shortcuts and expected readline support.
