D G Turner 617f6179c1 DREAMWEB: Change various loop variables to uint, rather than size_t.
This is partly for readability and partly to avoid any possible
portability issues i.e. though they should be the same, size_t is
defined by system headers, whereas uint is defined within our build
system.

Also, replaced a array size calculation with our ARRAYSIZE macro.
