- all .i files have been renamed to start with IMP_ to help make dependency tracking easier.

- static builds (builds with static=True) build both the static and dynamic libraries and just static executables. This means you should be able to run tests and stuff from static builds.

- the \c profile build target has been removed as \c static=True does the important bit of what is needed. Just add -pg to linkflags and cxxflags if you want to do use gprof.

- Restraints should now implement IMP::Restraint::unprotected_evaluate() instead of IMP::Restraint::evaluate(). The latter can now be called outside of IMP::Model::evaluate() and will return the right answer always.

- \c bin/imppy.sh no longer works, as was previously warned. Use \c tools/imppy.sh instead. The bin directory will go away eventually, for now the script just tells you to use the tools version.
