Subject: [PATCH] Make game name search case-insensitive

Serial uploader searches for games by filename (e.g., "tetris") but
games are registered by their metadata NAME field (e.g., "Tetris").
This caused launch failures when case didn't match.

Changed select_game_by_name() to use case-insensitive matching:
- strcasecmp() for exact match
- tolower() both strings before strstr() for partial match

Now uploading "tetris.lua" will successfully match and launch "Tetris".
