Vcproj file updates.

rplaces
     OutputDirectory="..\..\..\..\objs\debug\bin"
with
     OutputDirectory="$(SolutionDir)objs\$(ConfigurationName)\bin
and so on.

Rmoves
     OutputFile="..\..\objs\debug\lib\$(ProjectName).lib
when possible.

Also, in the current version "Whole program optimization" compiler option
is set, but the corresponding linker option isn't. From MSDN:
   "If you do not explicitly specify /LTCG when you pass /GL or MSIL modules
   to the linker, the linker eventually detects this and restarts the link
   by using /LTCG. Explicitly specify /LTCG when you pass /GL and MSIL modules
   to the linker for the fastest possible build performance."
So /LTCG option was added too.

Debug build now uses libogg_static.lib from .\objs\debug\lib folder.
(the dependency for both release and debug is
    objs\$(ConfigurationName)\lib\libogg_static.lib)
