Console command execution and command text buffering.
Any number of commands can be added in a frame from several different
sources. Most commands come from either key bindings or console line input,
but entire text files can be execed.
Command execution takes a null terminated string, breaks it into tokens,
then searches for a command or variable that matches the first token.
