Hugin

Part of the challenge in building the Hugin SDK is the copious amounts of
modification that have to be made to project files from the source
distributions.

This is a set of patches that performs the steps located at
http://wiki.panotools.org/wiki/index.php?title=Hugin_SDK_(MSVC_2008)&oldid=
11413 , which primarily involve converting VS 2005 projects to VS 2008 and
fixing paths to be relative to how the HuginSDK is built.

These patches also introduce configurations for the x64 platform. Where
applicable, a few x64 compile-related changes have been made as well to
facilitate compiling targeting x64.
