D343 M2: GE-styled options panel on file select; D344 docs

The file-select Options label opens a panel drawn in the same hook:
sections as tabs, rows from the F10 overlay's table via an exported row
API, the game's crosshair as pointer (input.c passes the stick, hands the
buttons to the panel). Quit to desktop now goes through videoRequestQuit.
Also repairs two escaped-newline typos in the D343 docs.
