rc/sfepy — Issue #7: (no) slip boundary conditions

Implement the slip/no-slip boundary conditions (u, n) = g, where u are the
displacements/velocities, n the normal of the domain boundary and g the
given slip (zero in no-slip case).

Note that in case of the mash aligned with the coordinate axes, the above
can be easily achieved by imposing proper Dirichlet BC. We wish to tackle
the case of general geometry.

Done, see input/biot_npbc.py - no penetration kind of LCBC.

It handles only the case (u, n) = 0, but the other case is not needed right now,
let's close this.
