Bug fix in RegionMesh::updateElementRidges. Once the boundary facets have been processed, the edges built from the elements are NOT on the boundary.

Destructor of MatrixEpetra and VectorEpetra MUST be virtual, since there are already other classes inheriting from it, and memory leak (at best) would happen if some of the derived classes is created on the heap.

removed a bunch of warnings: unused typedefs, deprecated methods, variables used only in debug (in which case we use the LIFEV_UNUSED macro)

boost::shared_ptr<>::value_type has been removed.

the pragmas are no longer needed since external library are now included
using the -isystem (or -i) flag that already disables all of them.

OseenSolver::M_localMap is a MapEpetra and not a pointer

This commit adds the support for specifying row and column offsets
when building FECrsGraphs or doing the FE assembly in with ET.

This functionality is needed for Stokes, Navier-Stokes problems
