Added binding for .., ..., ...., ....., and ...... in htdp languages.
...
Uses of these dots expand to an expression generating a runtime error
stating "expected a finished expression, but found a placeholder".
Students may write and run unfinished templates (as usual), but will get an
error message that is more specific and hopefully more useful than unbound variable.
Added tests for this functionality.
