vc8 solution assumes install location

<alert comment="tidy newbie">

Thanks for providing tidy.

I was attempting to build the source, and encountered problems because the 
..vcproj files assume that vc8 was installed in:
C:\Program Files (x86)\Microsoft Visual Studio 8\VC\

This line (repeated in several places) seems to cause problems .... can it 
be left out:
   InheritedPropertySheets="..\..\..\..\..\Program Files (x86)\Microsoft 
Visual Studio 8\VC\VCProjectDefaults\UpgradeFromVC71.vsprops"

I have vc8 installed in:
X:\DevTools\MsVisualStudio2005\VC

I was able to build tidy.exe and tidylib.lib with the line above removed (it 
is in multple locations in both .vcproj files)

Thanks.
