New release of Edge. The main new features in this release are as follows:

* Reordering

* New updating method for velocity and pressure

* Viscous spectral radius modified to improve convergence in areas
  with large viscosity.

* Periodic boundaries treated differently in a more consistent way,
  only convective fluxes added on these boundaries so far.

* Isothermal walls now treated with a weak boundary conditions.

* New turbulent DRSM models.

* Many minor bug fixes
