Make the SDL window honour monitor, --monitor and --list-monitors.

Browse Source 
On Linux the window ignored NX2NAVI_MONITOR (the log said it had no effect) and --list-monitors only printed that monitor selection is Win32-only. The SDL window now picks a monitor with the same rules as the Win32 one: auto (the system places it), primary, a 1-based index in listing order, or part of the monitor's name, ignoring case, the first match in list order winning. The monitors are SDL's displays; --list-monitors prints their index, name (the make and model, with the connector on Wayland and X11), pixel size and position, primary flag and display scale, then what NX2NAVI_MONITOR would pick, and the log says the same when the window opens.

The window is created centred on the chosen monitor and centred again at its final size, and that position also names the display the fullscreen setting covers, which is how a Wayland window, which a client cannot move, opens fullscreen on the chosen output. On Wayland a windowed window opens where the compositor puts it; the log says so once. With a chosen monitor, the size widescreen.c reads for fullscreen before the window exists is that monitor's.

The window opens on the monitor `NX2NAVI_MONITOR` (`monitor` in `nx2navi.ini`) names, and F11 fullscreen covers the monitor the window is on. `nx2navi.exe --list-monitors` prints each monitor's index, device name, name, desktop rectangle, primary flag and DPI without game files; `nx2navi.exe --monitor <value>` sets `NX2NAVI_MONITOR` for one run and wins over the file. The value is `auto` (default), `primary`, an index from the list (counting from 1), or part of a device name (`display3`) or monitor name; when nothing matches, the log lists the monitors and the window is placed as with `auto`. Windows only.

The value is `auto` (default), `primary`, an index from the list (counting from 1), or part of a monitor name (on Windows also a device name such as `display3`; on Linux the name carries the connector, such as `dp-2`); when nothing matches, the log lists the monitors and the window is placed as with `auto`. On Wayland a window cannot place itself: only fullscreen (`fullscreen = 1`) opens on the chosen monitor, and a windowed window opens where the compositor puts it.
The Minus+Plus combo never reaches the game. In the menu the arrow keys, the D-pad or the left stick move, Enter or A selects, Q and E or L and R switch tabs, Esc or B goes back (Switch button names, as in the table above).
