"no", "0", etc. to true/false.

  * options can now be spelled "foo-bar" or "foo_bar" (handled in
    'parse_config_files()', just after we parse a file)
  * added a "[global]" section so there's a place to set global
    options like verbose/quiet and dry-run
  * respect the "negative alias" dictionary so (eg.) "quiet=1" is
    the same as "verbose=0" (this had to be done twice: once in
    'parse_config_file()' for global options, and once in
    '_set_command_options()' for per-command options)
  * the other half of handling boolean options correctly: allow
    commands to list their boolean options in a 'boolean_options'
    class attribute, and use it to translate strings (like "yes", "1",
    "no", "0", etc) to true or false

- use unidb compression for the unicodedata module.  on Windows,
  the new unidatabase module is 120k, down from nearly 600k.

        avoid compiler warnings.

Handle the ****/**** appleevent wildcard when called as a main program, so that it becomes a handy debugging tool (BuildApplet, copy aete resource, apply applescript to it).

Added a workaround for shortcomings in the OSA support: there can be class/property conflicts and passing classes as arguments doesn't work. The package now seems to work.

xml.sax: Fix parse and parseString not to rely on ExpatParser
         Greatly simplify import logic by using __import__

Tiny bug fix to expatreader.py (endDocument was only called after errors).

db_185.h has renamed that function to __db185_open, which it does in DB 3.1.
So don't check whether the function is in -ldb.

The earlier code assumed "protocol=host;protocol=host;..." or "host",
but Windows may also use "protocol=host" (just one entry), as well as
"protocol://host".  This code needs some more work, so I'll leave the
bug open for now.

Bug fixes to XMLFilterBase (wrong ignorableWhitespace signature and
did not inherit set*Handler methods from XMLReader.)

tuple instead two arguments.

'spawnv' now, so we check for 'fork' first.
