Daniel Richard G 16179f34cd Enabled freeing of (most) allocated memory on program exit 
The Valgrind tool can give a full accounting of what memory allocations
have yet to be free()d when the program exits. It is easier to find actual
memory leaks in the code if all non-leaked allocations are elided from that
accounting, which is most easily accomplished by free()ing them.

The "most" qualifier is there because some allocations are difficult/
impossible to free, as they are internal to libraries like OpenGL and Xft.
The best we can hope for is to cover all allocations made by SolveSpace
directly.
