AnalyseCurvedMesh development (works for triangle and tetra but is not yet optimized and is still incomplete, edit PluginManager.cpp to activate the plugin)

fullMatrix : scale(0) in resize so that fullMatrix m(); m.resize(ni,nj); is equivalent to fullMatrix m(ni,nj);

Multiscale Laplace works 

- more work on slepc integration

- moved GUI to FlGui + added experimental QGui to test Qt

- fixed most MSVC and gcc compiler warnings

- converted some remaining tabs to whitespace (that's why the patch is
  so large; please try to remember to indent with 2 spaces and not
  tabs when you commit stuff to CVS)

- merged modified patch from Konstantinos Poulios to allow saving
  physical/partition as element tags in mesh formats that don't
  support them natively
