[ublas] umfpack bindings bug+fix

Hello,

I experienced de-allocation problems in the UMFPACK bindings.
The diff you find below fixes the bug by adding a constructor  to the  
symbolic_type and numeric_type structs that are defined in bindings/ 
umfpack/umfpack.hpp .
The ptr variable will now be initialized to 0.

Can someone add this to the svn repository?

Kind Regards,
Bart Janssen
