Use 'int' instead of 'unsigned int' or 'short'

[richelbilderbeek]

In the class scoreboard there are those fancy datatypes called 'unsigned int' and 'short'. It is recommended to always use int (see Scott Meyers, 'Efficient C++' and 'C++ Coding Standards: 101 Rules, Guidelines, and Best Practices' by Sutter & Alexandrescu).

Reasons are:

• the one bit does not matter sizewise,
• the one bit is actually useful to detect errors
• using short is premature optimization: we do not need to save those couple of bytes
