[GSAS-II] GSAS-II self-updating bug fix for Windows

[Brian Toby]

I have addressed a bug that was preventing GSAS-II from updating properly on some versions of Windows (-7 or possibly -Vista & later). This bug prevented certain binary (.pyd) files from being overwritten, since GSAS-II uses them. The error message shows as "svn: Can't move <file> to <file>: Access is denied" in the console (see https://subversion.xor.aps.anl.gov/trac/pyGSAS/attachment/ticket/11/Capture_8_29_1.PNG). Note that this problem did not affect folks using the Mac, Linux and Win-XP. 

Starting with the version of GSAS-II uploaded today [1048], this problem is avoided by restarting GSAS-II during an update, but you might have trouble getting the update to complete to get to that version due to the bug. There is a simple work-around if this is the case: 

  1) exit any GSAS-II sessions that are running 
  2) run the bootstrap.bat file in the \GSASII directory

Thanks to Anna Płonka and Vic Young for reporting the problem.
