Rouge::Lexer#debug

Instead of `debug { "foo" }`, simply `puts "foo" if @debug`.

Leave a debug message if the `:debug` option is set.  The message
is given as a block because some debug messages contain calculated
information that is unnecessary for lexing in the real world.

Calls to this method should be guarded with "if @debug" for best
performance when debugging is turned off.
