Empty Bounds sections should be allowed

[ahenshaw]

With binary-variable problems, Gurobi will insert a Bounds section that only has the line "Bounds". Like so:

\ LP format example

Minimize
obj:  x + 10 y
Subject To
r01:  x + y  >= 1
Bounds
Binaries
 x y
End

This seems to cause the parser to miss the "Binaries" line.

Thanks for raising. I'll fix this in the morning.
