Speed up BT export to subversion working copy

Main optimization consists in reducing disk writes, by not using 'copytree'
anymore. Only modified/new files are copied from the temporary folder.

Also drop 'copyTree' and 'cacheWalk' because they are unused and 'dircache' is
deprecated.

#A. HISTORY OF THE SOFTWARE
#==========================
#Python was created in the early 1990s by Guido van Rossum at Stichting
#Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands
#as a successor of a language called ABC. Guido remains Python's
#principal author, although it includes many contributions from others.
#In 1995, Guido continued his work on Python at the Corporation for
#National Research Initiatives (CNRI, see http://www.cnri.reston.va.us)
#in Reston, Virginia where he released several versions of the
#software.
#In May 2000, Guido and the Python core development team moved to
#BeOpen.com to form the BeOpen PythonLabs team. In October of the same
#year, the PythonLabs team moved to Digital Creations (now Zope
#Corporation, see http://www.zope.com). In 2001, the Python Software
#Foundation (PSF, see http://www.python.org/psf/) was formed, a
#non-profit organization created specifically to own Python-related
#Intellectual Property. Zope Corporation is a sponsoring member of
#the PSF.
#All Python releases are Open Source (see http://www.opensource.org for
#the Open Source Definition). Historically, most, but not all, Python
#releases have also been GPL-compatible; the table below summarizes
#the various releases.

#Footnotes:
#(1) GPL-compatible doesn't mean that we're distributing Python under
#the GPL. All Python licenses, unlike the GPL, let you distribute
#a modified version without making your changes open source. The
#GPL-compatible licenses make it possible to combine Python with
#other software that is released under the GPL; the others don't.
#(2) According to Richard Stallman, 1.6.1 is not GPL-compatible,
#because its license has a choice of law clause. According to
#CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1
#is "not incompatible" with the GPL.
#Thanks to the many outside volunteers who have worked under Guido's
#direction to make these releases possible.
