This fixes PR#211.

	A change in my last patch could, under certain circumstances,
	cause a loop if the connection to the server dropped while
	waiting for a command completion. I've changed the code to
	re-raise the error after possible debugging output.

of the current module.  It also runs the tabnanny to catch any
inconsistent tabs.

Also did a little bit of refactoring: added an errorbox() method to
simplify the display of error dialogs.

PyEval_EvalCode() is *not* a "backward compatible interface", it's the
one to use!

enough, it could be negative.  Add i > 0 test.  (Not i >= 0; zero isn't
a valid error number.)

Added FreeMem, MaxBlock and CompactMem calls. The values returned by these are lower bounds in the Python case (as malloc doesn't return memory to the heap) but they can be used to decide when to give low-memory warnings.

	The same problem (mixed mallocs) exists for the pcre stack.
	The buffers md->... are allocated via PyMem_RESIZE in grow_stack(),
	while in free_stack() they are released with free() instead of
	PyMem_DEL().

	The buffers self->regex and self->regex_extra are allocated in
	pcre_compile() and pcre_study() via pcre_malloc, but are released
	via free() instead of pcre_free.

  add clsFilesystemImporter class attribute, alter handling of suffix list
convert suffix importers to funcs rather than instances
remove backwards compat code: Importer.install and 2-tuple get_code()
  result values

switch to isinstance() rather than direct type comparisons
removing chaining concept
update ImportManager.install() to take an optional namespace to install
  itself in. this will be useful for setting up rexec environments.

old 'dist' command, but the code for dealing with manifests is completely
redone -- and renaming the command to 'sdist' is more symmetric with the
soon-to-exist 'bdist' command.

- removed now (happily) unused second arg
- need to verify results of [].index are correct; for building consts,
  need to have same value and same type, e.g. 2 not the same as 2L

(big surprise).  new solution is a little less hackish.

Code gen adds a TupleArg instance in the argument slot. The tuple arg
includes a copy of the names that it is responsble for binding.  The
PyAssembler uses this information to calculate the correct argcount.

Swapped the order of the descriptions of int() and intern() so that
int() comes first (the functions are in alphabetic order).
