Recalculate shop prices before giving money back on sold items.
...
This fixes a bug where one could get more than half the item price back. In
particularly, a level 2 Plasma Cooling Booster would sell for more than you
bought it for.
This fixes Debian bug #253380 .

Don't blit unnecessarily.
...
During the game, a lot of images were blitted outside the visible area. Also,
addBuffer() was called even when the destination surface was not the screen,
resulting in unnecessary blits in unBuffer().

Use textSurfaces instead of calling drawString() in doInfo().
...
This increases efficiency significantly. Before, callgrind estimated that 58%
of the CPU time was spent in doInfo(), taking roughly 1.6 kcycles on average
per call. After, only 0.13 kcycles on average per call are used (12x speedup),
and only 14% of the CPU time is spent in doInfo().

Slightly increase intro text scrolling speed.
...
Scrolling 1/4 pixel per frame results in jerky motion, mostly because 4
times 16 2/3 milliseconds is not a round number. Scrolling 1/3 pixel per
frame results in much smoother scrolling.

Use SDL_DOUBLEBUF in all SDL_SetVideoMode() calls, and don't force 16 bits.
...
By forcing 16 bits for full screen mode, performs drops dramatically on
displays where SDL has to do conversion.

Enable double buffering.
...
This seems to improve performance (probably because this prevents the
need to lock the screen surface), and might get rid of tearing.
