boost.cmake: Added several more components.
Added chatty C++/python logging library.
Added lemon graph library.
Added cylemon (python bindings for lemon graph library implemented with cython).
ilastik-gui: Added chatty and cylemon as dependencies, and added carving workflow launch script.
- cylemon is needed for the carving workflow
- chatty isn't really needed for ilastik per se, but will probably be needed in future workflows.
ilastik.cmake: Updated git tag.
numpy.cmake: Updated to numpy 1.7.0 (there is a known bug in 1.6.x that conflicts with h5py)
ilastik-gui.cmake: Fixed a typo in the cylemon dependency.
ilastik.cmake: On Mac OS, rename the drtile.dylib library to drtile.so, since Python seems to insist on that name.
ilastik-gui: Don't include chatty.  It didn't belong here in the first place, and doesn't build on Mac.
lemon.cmake:
- Explicitly disable GLPK support
- Added a comment about (lack of) clang support for this package.
ilastik-gui.cmake: Fixed a typo.
vtk.cmake: Explicitly disable tcl bindings.
