ascii-invaders 0.1b

ascii-invaders project is a clone of Space Invaders which uses the curses library.
t compiles and runs on MacOS X, GNU/Linux and probably any other system with a curses implementation. I tried to reproduce the way the aliens move in the real game (which you can play on the MAME emulator on a modern computer system). It looks better than it plays however.
I wrote it some time ago in a fit of the-way-computers-were-nostalgia. Perhaps Ill have a go at insulting another classic game in the same way soon.
While writing the game I was inspired to write a deranged rant about the joy of terminals, command lines, Unix, curses and vi.
If you need to change Ascii Invaders to build it on another platform, Id be grateful for patch or instructions so I can include them. Likewise, fixes and improvements to the ascii-art or the code are very welcome. Id also love to hear whether its actually usable on a real serial terminal :-)
Enhancements:
- fixed time() call
