This patch adds CurrentByteIndex, CurrentColumnNumber,
CurrentLineNumber members to the
xml.parsers.expat.XMLParser object which respectively
wrap the XML_GetCurrentByteIndex,
XML_GetCurrentLineNumber, and
XML_GetCurrentColumnNumber expat functions.

Oops - obviously CurrentColumnNumber wraps
XML_GetCurrentColumnNumber, and CurrentLineNumber wraps
XML_GetCurrentLineNumber.

The patch looks good to me after a quick glance and test
run. Maybe add something to the test suite to exercise these
attributes? It should be as easy as adding print statements
to a handler or two (the test relies heavily on comparing
the output to a known one). Most of the other attributes
aren't tested-for by the test suite, though. \versionadded
in the docs might be nice, too--just once, after the
paragraph introducing them.

Have added a unit test to check that the Current* members do
return something useful for parser events.  Decided against
testing character data events as there can be more than one
per section of character data - this might be fragile in the
face of newer expat versions.

Oh, also added a \versionadded.  Will apply this patch.
