Fix all warnings on MSVC 8 (.net 2005), add support for VS Express edition 2005, changed build to use vcbuild instead of devenv, reduced the number of out of tree project files we are managing in tree by patching the files as necessary in scripts.  Now only sqlite (which does not come with a project file) and apr (which does not come with a vcproj, only dsp file) are managed in tree.  We still need to come up with a way to convert dsp to vcproj files in vbscript.
