py3: keep "keypressed" a native str in crecord

This will help in the next changeset by avoiding a decode step. Also,
the actual bytes conversion seems superfluous since values coming from
curses's getkey() will be a native string. As a consequence, we open the
"testcommands" file (used in test-interactive-curses.t) in text mode.

{
    // Enforcing
    "eqeqeq"        : true,     // true: Require triple equals (===) for comparison
    "forin"         : true,     // true: Require filtering for..in loops with obj.hasOwnProperty()
    "freeze"        : true,     // true: prohibits overwriting prototypes of native objects such as Array, Date etc.
    "nonbsp"        : true,     // true: Prohibit "non-breaking whitespace" characters.
    "undef"         : true,     // true: Require all non-global variables to be declared (prevents global leaks)

    // Environments
    "browser"       : true      // Web Browser (window, document, etc)
