Subject: [PATCH] Fix mismatched usage length, build fail on g++
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The length of const option::Descriptor usage[] is intended to be
inferred based on the initialisation in Source/main.cpp, however, the
extern declaration in Source/Game.hpp hard-codes it to 13.

Remove the hard-coded 13 in the extern declaration, in favour of the
inferred length.

This also fixes the follwoing build failure with g++ (Debian 4.9.2-10)
4.9.2:
