"New", nicer solution for including the SVN revision information in Windows builds.

Originally committed to SVN as r1170.

+// This file is intended as a template for the TortoiseSVN tool SubWCRev
+// Set up your project so it runs a command similar to this as pre-build event:
+//"C:\Program Files\TortoiseSVN\bin\SubWCRev.exe" "$(SolutionDir)../aegisub" "$(SolutionDir)../aegisub/build/svn-revision-base.h" "$(SolutionDir)../aegisub/build/svn-revision.h"
+// Of course make sure the relative paths etc. match your system
+
+// Do not add or commit the resulting file to SVN.
