Only the 2008 version is kept up to date at the moment.
The newer versions of MSVC can open and upgrade the 2008 version
files anyway, so by removing the unmaintained ones we reduce the
confusion and maintainance burden.
Additionally, the preferred way of building with MSVC is with the
makefile build system, according to the readme.
Instead just link directly to it. This matches how the library is
linked/loaded in encConsole/h264enc as well.
Only the 2008 version project file is updated for now, since
the 2010 and 2012 ones are out of sync right now.
These files are unmaintained and outdated, not even functional
in the initial commit of the project. Additionally, no similar
files are present for the decoder.
