Added script from another vss2svn branch for git

From <http://vss2svn.googlecode.com/svn-history/r354/branches/Alexander/ssphys/configure.ac>
for svnwcrev.sh that works with git.
Fixes for updated Module::Build, missing required modules.
Replaced Config::Ini with Config::Tiny.
Changes for Boost 1.50.  Builds.
Applied patch for 64-bit Linux.

Applied most of `svn diff -c 354 http://vss2svn.googlecode.com/svn/branches/Alexander`
Hopefully this will make 64-bit Linux builds work.
Applied patch for 2GB file (issue 7) replacing their choice of type with off_t.

Issue 7 is : <http://code.google.com/p/vss2svn/issues/detail?id=7>.
Most of the long32 objects go away with this patch.
Updated TinyXML-1 from 2.4.3 to 2.6.2.
Added GitAction table.
Output task info and log task times.
Use File::Find a little bit better.
Removed local variable.
Added constant Vss2Svn::ActionHandler::VSSDB_ROOT.
Scrub '\r' from svn:log.
Fixed warnings.
These changes fix data for simple RESTOREs.

They would both kill data when a project is subsequently RESTOREd.
Added datapath field to Physical table.

Might as well remember where we found the file when finding VSS
database files.
Changed GetPhysVssHistory and GetVssPhysInfo to use Physical table datapath.
Remove FindPhysnameFile.  Not needed anymore.
Modified script for git use only, since it's now hosted at github.
