first attemps to make properly linearized version of mortar projection for finite sliding. not working at the moment, it has convergence issues.

Incremental formulation works now, also finite sliding without proper linearization (very slow convergence)

removed obsolete (and potentially non-meaninful) test routine for elements. for nonlinear geometry we need to have some good way to distinguish between initial and deformed coordinates

Major changes in data structures:
...
- Combined FieldAssembly and BoundaryAssembly to Assembly
- Combined FieldProblem and BoundaryProblem to Problem
- FieldProblem and BoundaryProblem are now abstract types
- Renamed stiffness_matrix, mass_matrix and force_vector to K, M, f for
easier notation
- Problems are no more abstract types but concrete types, see
elasticity.jl for example
- Combined linear_elasticity.jl and elasticity.jl
- Removed obsolete code directsolver.jl
- Almost all tests probably fail at this point
