699c40643d * Changed setup-plt to compile collections if they have an "info.ss" 
file.  (That is, it does not require the file to have a `name'
  entry.)

* The name shown when setup works is the directory name, followed by
  the `name' field from the info file when specified.

* This means that many `name's are no longer needed, so I'm removing
  them.  To see if you need a `name' entry, consider that the name
  will be shown like this:
    ... foo (<your name here>)
  This means that if the name is the same as the directory name, then
  there is no point in having it.  I also removed cases where the name
  differed only in its capitalization for collections where the case
  is obvious.

* Also, for subcollections, the name should clarify the name of the
  subcollection in context.  For example "Acknowledgments" explains
  what scribbling/acks is, but there's no need to add the context name
  as in "Scribblings: Acknowledgments".

* There may also be a point in keeping names for other uses.  One such
  example was in games, where the name field was used in the PLT Games
  application.  (This was changed to default on the directory name, so
  it is no longer needed in most games.)  Another example is in planet
  packages.

5b67fcbb86 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.
