Ben Harris df783b93e3 Avoid division by zero in Cube grid-size checks 
On a triangular grid, Cube allows either d1 or d2 (but not both) to be
zero, so it's important to check that each one is not zero before
dividing by it.

The crash could be triggered by, for instance "cube t0x2".

README 

This is the README accompanying the source code to Simon Tatham's
puzzle collection. The collection's web site is at
<https://www.chiark.greenend.org.uk/~sgtatham/puzzles/>.

The puzzle collection is built using CMake <https://cmake.org/>. To
compile in the simplest way (on any of Linux, Windows or Mac), run
these commands in the source directory:

  cmake .
  cmake --build .

The manual is provided in Windows Help format for the Windows build;
in text format for anyone who needs it; and in HTML for the Mac OS X
application and for the web site. It is generated from a Halibut
source file (puzzles.but), which is the preferred form for
modification. To generate the manual in other formats, rebuild it,
or learn about Halibut, visit the Halibut website at
<https://www.chiark.greenend.org.uk/~sgtatham/halibut/>.
