BEM++ does not link to armadillo anymore

It should be sufficient that it links to blas and lapack directly.
Update to cmake 3.0

Seems to have changed the way static library dependencies are exported.
Updating to dune version 2.3.1

External project now compiled via Dune's own cmake.
Also, added umbrella target Dune that depends on all the dune sub-components.
This may be one of the problems affecting parallel builds (#115).

This commit goes partway to #114 (dune update) while still retaining static
linkage (#116). The code compiles, but there is a bug in one of unit test over
the foam grid. Might be that the dimensionality of the problem is not passed
correctly to foamgrid somewhere.
Easier to find imported libraries BEM++ depends on

There seems to be some difficulty for external project to find libraries the
BEM++ links to by importing them.
Was linking BEM to not yet existing libraries

Must link BEM++ to external libraries built within BEM++ with some care.
