flatten argument list to _create before passing on to tk.call;
	_do should return a value.

	Renamed tkerror to _tkerror, default_root to _default_root.
	(_substitute, _subst_prefix): move back into class Misc; added
	widget Event attribute.
	Added functions that return widgets or widget lists:
	winfo_children; focus_get; grab_current.
	(Pack.slaves, Place.slaves): return Widget objects instead of
	pathnames.
	Renamed __del__() to destroy() (because of circular refs, __del__
	won't ever be called).
	Added some names with explicit _set: focus_set, focus_default_set,
	grab_set.
	Added focus_default_none.
	(Misc._getints): use tk.splitlist() instead of tk.split(), return
	None if string empty.

Removed redundant global statements
getboolean returns None if argument is empty
AtInsert() concatenates optional arguments after 'insert'

Added usage message to test program.

In Pythonrun, tirn off SIGPIPE and move signal handlers elsewhere.
In ceval.c, also move locals_2_fast/ fast_2_locals to frameobject.c,
replaced local variable trace by f->f_trace, got rid of unused
mergelocals() and unneeded calls to fast_2_locals, return the variable
name on "fast variable not found", AND use "__call__" method if it
exists to call an inmstance.  Whew!
