Update lp_solve port

Main changes:

15/09/16 version
- When using set_lowbo and set_upbo to set bounds on a variable and the new low/up bounds are very close to each other
  but not equal then they are set equal for numerical stability.

18/09/16 version
- When all variables in the model are integer, but not all binary (in fact difference between upper and lower bound 1),
  then it could happen that not the most optimal integer solution was found.
- Updated/added scaling options to the lp_solve command line program
