* Add unit test to exercise Collector #1959, "FieldIndexes won't store
  Zero's" (but I can't verify the hypothesis, dammit!)

Changed getobject logic to log on failure and raise a meaningful exception instead of raising unauthorized and causing a browser auth box to pop up.

extra semicolons at end, like Python allows extra commas.

compiling directly from DOM!

Most expression compilation has moved to TALGenerator (exceptions for
now: attribute replacements and macro name).

allows such a module to import other modules in the same directory.

Raise error in _getobcontext if request.steps is len(0)... if someone deletes the root index_html, they will no longer get a puzzling failure if they attempt to view an object without an acquirable index_html.

Fix reference to local variable; also submitting patch to Steve Purcell.

Changed product init code so that README.txt can be any of "README.txt", "README.TXT" or "readme.txt".

we can rerun the tests and catch exceptions witha debugger.

namespace declaration.

- Only minimize empty elements when the content model is empty,
  keeping an explicit list of which elements have an empty content
  model (e.g. <img>, etc.).  This checks whether the tagname is in an
  explicit list of such elements; the check is case insensitive.

- Minimize certain attributes that are considered Boolean by HTML,
  e.g. ismap.  Again, this does a case-insensitive check whether the
  attribute name is in a list of known Boolean attributes.

Note: this should really be refactored, making HTML support a subclass
rather than a keyword argument.  Later...
