AmiSC 68K v0.1.1 - command card icons fixed

Bug-fix release. Replaces v0.1.0 — use this one.

Fixed: the command card was blank when the data came from the modern free
re-release. The icon set moved between releases (unit\cmdbtns\cmdicons.grp
in the original, unit\cmdicons\cmdicons.grp in the modern one) and the port
only looked for the old name, so every button fell back to plain text. It now
accepts both.

Clearer program names. SC → SC_RTG, SC_lores → SC_RTG_lores,
SC_MENU → SC_universal. Start with SC_universal: it detects the
display itself and lets you switch between all four modes (RTG or AGA, 640×480
or 320×240) from the menu while it runs. The other four have the display nailed
down, for comparing modes.

Everything else is as in v0.1.0 — including the alpha-state list: unfinished
computer opponent, no unit costs on the buttons, units occasionally crossing
terrain they should not, oversized minimap on large maps, no sound, no
campaign, no multiplayer. You bring your own copy of the game's data; both the
original and the modern free release work.
