Script would crash when a file in AccuRev was set as read only.

PermissionError: [WinError 5] Access is denied: 'D:\path\to\readonly\file.txst'

This change catches the exception and then removes the readonly flag, and tries to delete the file a second time.

Note: I ran into this problem on Win7, Py 3.4, AccuRev 7.0, Git 2.16.1.windows.1

The files became read only because we use AccuRev's exclusive lock feature, which checkouts a file as read only, unless you have the lock on it.
