- [SCONS] Adding the creation of an Object Browser database (Source browser in MSVC6) when building a debug binary.

This is contributed by Jonathan Harris. I paste here his comments for further reference:

MSVC will open the database automatically when you debug blender.exe.
The database needs to be explicitly closed before rebuilding by removing
it from the MSVC7 "Solution Explorer" window. Add it back after the build.

TODO: .sbr intermediate files are created in the build tree. These
should be removed by a clean but aren't.
