Arie Gurfinkel d06f4bd337 Fix reset of params_ref in solver 
params_ref is not a ref, and params_ref::reset is not ref::reset.

params_ref::reset resets the params object being pointed to by
params_ref.

A proper way to reset a params_ref as a reference is to assign an
empty params_ref object to it.

Dan Liew 4b517b96df [CMake] Move CMake files into their intended location so the 
`contrib/cmake/bootstrap.py` script no longer needs to be executed.

The previous location of the CMake files was a compromise proposed
by @agurfinkel in #461. While this has served us well (allowing progress
to be made) over time limitations of this approach have appeared.

The main problem is that doing many git operations (e.g. pull, rebase)
means the CMake files don't get updated unless the user remembers to
run the script. This can lead to broken and confusing build system
behaviour.

This commit only does the file moving and necessary changes to
`.gitignore`. Other changes will be done in subsequent commits.
