REDcode 0.8.1

The first version on the VS Code Marketplace and Open VSX, as a Preview. 0.8.0 did not reach them: the Marketplace refused its display name. Needs REDbridge 0.8.0.

• The display name is now REDcode for Cyberpunk 2077. Marketplace display names are unique across publishers, ignoring case, and "redcode" is taken by an extension for Core War's Redcode language. The id stays edgemodders.redcode, so settings, commands and keybindings are unchanged.
• The first-run game folder offer no longer activates REDdeck to ask for its game path; it asks only when REDdeck is already running, and stops once REDcode is deactivated. Activating REDdeck there raced a window reload, and VS Code warned that REDdeck's output channel went into a disposed store. Found while looking into an intermittent startup abort (exit code 134) of the development host, whose cause is still unverified.
