EIGEN_DONT_ALIGN_STATICALLY compilation option was added for Win32 only in revision 41283 because of some compilation problem. But this option is causing alignment problem for Eigen3 local variables when SSE optimization is enabled. I do not have any compilation problem when the option is not defined, so I just remove it as it should.

That static align trick i've wrote about is still necessary.

- Upgrade Eigen2 library to Eigen3
- Upgrade colamd library and placed in extern/ so other libraries from extern/ can use it
NOTE: With previous version of Eigen (3.0.1) it was necessary to define
EIGEN_DONT_ALIGN_STATICALLY macro to make it compilable on windows 32bit.
After latest upgrade it seems to be unnecessary (at least when was testing libmv),
so i removed that defines which can reduce speed and lead to other problems.

blender_add_lib now takes a separate include argument to suppress warnings in system includes (mostly ffmpeg & python).
also only build wm_apple.c on apple+carbon configuration.

and endif() which is no longer needed.

reporting missing headers & C files.
this is important so IDE's using CMake integration always get blender headers. - QtCreator & MSVC for eg, probably others too.

getting the blender version twice and not working sometimes.

by cmake devs.
globbing vs explicit is discussed here.

Practical implications are:
- developers need to keep CMakeLists.txt files up to date.
- Users wont get strange linking errors if they build after a file is added, since CMake detects CMakeLists.txt is modified and automatically reconfigure.

- option only available to cmake, scons and make have this enabled always.
- without this clang/llvm can compile blender
- this was the second biggest internal lib, 192mb -> 172mb for all blenders libs (with debug flags), so gives some speedup to linking.

Makefile updated but not tested. Comes with Eigen2 2.0.6 C++ matrix library.
