Anotheer build system change, this time related to vs-win32 builds
* created a ADD_LOADER macro to simplify things a bit
* Split util from boomerang as a static library - the overloaded stream
operator for ADDRESS is used in Elf and Win32 BinaryFiles
* changed exe/dll output directory setting to work properly on windows,
now all built files are properly put into PROJECT_ROOT/out/
PROJECT_ROOT/out/lib directories
* Under win32 added DbgHelp to targets that need it.
