[Chandler-dev] PyICU no longer uses SWIG

As of release 0.5, on the PyICU development trunk, SWIG is no longer used.
Instead, the Python object wrappers are implemented by hand using the Python C
The handwritten wrappers represent about 12,000 lines of C++ code, a lot of
boilerplate. Although macros are heavily used, the rather repetitive nature of
this code makes it easy to make copy/paste mistakes along the way.
The few PyICU unit tests are passing but I expect typos and mistakes to still
be lurking. If you find something wrong, it'll most likely crash or report an
InvalidArgsError that should be trivial to fix by following the general
argument passing patterns used with parseArg() and parseArgs(). Please report
these bugs and/or submit patches to fix them.
I also changed all methods that return a mutable ICU UnicodeString to return
an immutable python unicode string instead. If a mutable ICU UnicodeString
object is actually desired, all these APIs accept an additional UnicodeString
argument (usually in the position of the ICU API's UnicodeString& parameter)
that will be modified in-place with the return value.
