Fixed typos on cli errors.
Fixed a typo on description for setuptools command option.
Python3

Without 'b' option, using python3 everybody will get during update:

Update classifiers to give more detailed information about babel's version compatibility
Correctly parse number pattern with '-' on the end

For the nl_NL locale, negative numbers would be formatted just like
positive numbers by format_currency. By changing NUMBER_TOKEN to
no longer have a minus sign in it, the minus sign on the end
of the negative pattern for nl_NL is correctly parsed.
Reformatted import script
Add links from changelog entries to their ticket via extlink

Supports links to the new github (``:gh:``) and the old trac
(``:trac:``). The prefixes are used to keep the same reference style
as pre-extlinks in the final output (aside from a few entries at the
bottom of 1.0, trac references were all in the form ``ticket #42``).
Fixup get_currency_name test

This test failed in environments where no default locale
can be determined; make the test deterministic and add
additional test for plurality.
