AmiSC 68K v0.2.0 - the interface stops being silent

The interface stops being silent.

Costs on the buttons. Hover over a build, train, research or upgrade button
and it shows minerals, gas and supply. Red when you cannot afford that one.

Research and upgrades now have a progress bar and a CANCEL button. The
command card used to go blank for the whole duration.

Refused orders now say why — red text above the minimap: not enough
minerals or gas, build more supply, queue full, cannot build there.

Still open: weak computer opponent, oversized minimap on big maps, no sound,
no campaign, no multiplayer.

Start SC_universal. No game data included — see
HOW_TO_LOAD_PC_FILES.txt. No FPU required.
