Added the core of the AI wake computations with its tests.
...
At the moment, this is dead code: only the tests are compiled. FG is still compiled without this code.
A new directory is created that contains all the numerical computations made to estimate the wake induced by AI aircrafts. This is based on the venerable Vortex Lattice Method (VLM) which was all the rage in the 60's Computational Fluid Dynamics (CFD).
Even though quite old, the method is relevant to compute aircrafts wake in real time since 3D Navier-Stokes (NS3D) is out of reach for real time computations even with modern multicore personal computers and their GPUs.

Fixed LaRCSim matrix computation routines.
...
There was a couple of typos in the routine. This code will be used by the AI wake feature.
Also added a test for the matrix code to make sure they will be no regression.

External moments can now be specified in addition to external forces. This feature is needed for the AI wakes.
Headers clean up to reduce the amount of recompilation when modifying an header file.

Fixes to the trim on ground feature.
...
* Skip the gears when located over water. They will be skipped by the ground reactions anyway making the trim irrelevant.
* Ignore the ground bumpiness during the trim. The trim algorithm seems not to
be robust enough to handle that. This does not make much difference to the
converged solution anyway since the bumpiness is generally low.
* Fixed the WOW status for contacts over water (was 'false' is now 'true').
* All the gear/contact data are now properly reset when WOW==false. The reset
code is now common to all the case where WOW is false.
