Different MIP backend implement write_lp, write_mps in different ways, in particular regarding filenames (is the extension ".lp" added?) and what they do regarding the objective sense (min/max).

Document this and unify if possible.

In particular, compare for the COIN backend's and the GLPK backend's write_lp output for maximization problems.
