Ported Config.py from optparse to argparse

[brainwane]

In this change, I've ported Config.py from using optparse (which is now deprecated) to using argparse.

An OptionParser object used methods:

• add_option
• add_option_group
• parse_args

An OptionGroup object used:

• add_option

Both of these are replaced by ArgumentParser, which uses:

• add_argument
• add_argument_group
• parse_args

Additional cleanup in this change:

• moved positional-vs-keyword argument logic and precedence into argument setters (line 170-174, was 217-223)
• updated imports of modules (some were unused)
• changed Config to a new-style class
• updated copyright date
• removed extraneous whitespace

OK, just tested this and saw:

./bicho --db-user-out=root --db-password-out=[password] --db-database-out=bicho_test -d 15 -b bg -u "https://bugzilla.libresoft.es/buglist.cgi?product=bicho" Traceback (most recent call last): File "./bicho", line 8, in <module> retval = Bicho.main.main() File "/home/sumanah/test/Bicho/Bicho/main.py", line 45, in main Config.set_config_options(usage) File "/home/sumanah/test/Bicho/Bicho/Config.py", line 150, in set_config_options default='5') File "/usr/lib/python2.7/argparse.py", line 1286, in add_argument raise ValueError('%r is not callable' % (type_func,)) ValueError: 'int' is not callable

So this still needs a little work.
