It's just used in this one place, and isn't very large. Also move things
around a bit to avoid having to define new complex types.

Fix some indentation issues and make sure everything* uses CamelCase.

* MonitorArrangement is left as snake_case in order to pretend it is an
  independent FLTK widget class.

It might be useful to have more information about a monitor when
configuring its settings in the Options menu. Therefore, this commit
adds support for showing additional information about a monitor
(resolution and platform-specific name).

This covers some Alt+key presses as well.

Some of the virtual key codes for Japanese keys are used for other
things on other layouts, so we need to make sure we only use this look
up table when the layout is indeed set to Japanese.

Added vkey mappings for Japanese keyboards because the special keys for Japanese input do not work on TigerVNC currently.

Improve AltGr detection even further on Windows so we can detect the
case when Ctrl and AltGr are pressed together.

Ctrl+Pause sends break which results in a different VKEY on Windows.
Make sure we map that properly to the equivalent keysym.

This key requires a bit extra care on Windows. We get wildly
different messages depending on if Alt is pressed or not. The symbol
chosen now follows the standard behaviour on X11.
