Bind ctrl-Z to redo (since ctrl-z is undo)

Browse Source 
In addition to the native Emacs undo binding, we also support ctrl-z.
On Linux, ctrl-shift-z alias ctrl-Z is the redo binding according to
https://en.wikipedia.org/wiki/Table_of_keyboard_shortcuts Let's bind allow
that.

Unfortunately ctrl-shift and ctrl-alt modified shortcuts on Linux may be
intercepted by the windowing system or the terminal. Only alt-shift seems to be
available reliably (but the shift bit should mean "extend selection" in Emacs).
