Visual Studio 2005 and above defaults to disabling the startup banner
for the Compiler, Linker and MIDL tools (with /NOLOGO). As such there
is no need to explicitly set the SuppressStartupBanner directive, as
this is a leftover from the VC7 and VC7.1 projects being upgraded to
VC8 and above.
Defined the DEBUGBUILD pre-processor variable to allow extra logging,
which is particularly useful in debug builds, as we use this and Visual
Studio typically uses _DEBUG.
We could define DEBUBBUILD, in curl_setup.h, when _MSC_VER and _DEBUG is
defined but that would also affect the makefile based builds which we
probably don't want to do.
Removed the WIN64 pre-processor definition from the libcurl project
files as:
* WIN64 is not used in our source code
* The curl projects files don't define it
* It isn't required by or used in the platform SDK
* For backwards compatability curl_setup.h defines WIN32
* The compiler automatically defines _WIN64 for x64 builds
Historically Visual Studio projects have defined WIN32, in addition to
the compiler defined _WIN32 definition, and I had incorrectly changed
that to WIN64 for the x64 libcurl builds but not in the curl projects.
As such, it is questionable whether this should be defined or not. For
more information see the following cache of a discussion that took
place on the microsoft.public.vc.mfc newsgroup:

As with commit 11397eb6dd, use $(TargetDir) and $(TargetName) for the
Import Library output rather than $(OutDir)\$(ProjectName)d.lib and
$(OutDir)\$(ProjectName).lib.
Unlike previous versions of Visual Studio the VC12 solution file format
does not increment the format version number, but instead, only changes
the version comment text.
This incorrectly set version number would cause problems for any third
party piece of software that would read the solution file expecting the
version number to be 12.00 and found it to be 13.00, such as some build
accelerators.
Verified against a freshly created solution file which was generated
with VC12.
Carrying on from commit 11025613b9 added VC12 project files which are
capable of supporting side-by-side compilation, 32-bit and 64-bit
builds as well as support for some of the third-party libraries curl
uses.
