First official release of the open source COOLFluiD

This code version includes the core COOLFluiD framework and numerical solvers for flows and plasmas on unstructured meshes. In particular, this version includes a bunch of new features which have been developed within the last year (2016/2017): support for static linking (it was broken before), (GPU-enabled) ion-electron and ion-neutral multi-fluid plasma model, flux reconstruction method, finite volume-based radiation algorithm, interface to PARALUTION for solving linear systems on GPU.

This release is the very first one since when COOLFluiD was uploaded to Github in October 2014, however it was decided to start the versioning number directly from 2.0.0 given the maturity of the code (whose development actually started in 2002 on private repositories and continued full speed up to now...).
