Hi all,

I'm having so much fun with BOH that it looks like I can't stop producing updates

Here's what update5 does:
* replaces low obstacles with traps (f.ex. the pools of the theme "default" cause damage to the shield);
* adds dynamic sound to traps animations;
* adds acoustic feedback to shield discharges;
* improves the sound engine policies;
* simplifies and improves the automapper colors (dangerous places are indicated more clearly);
* increases the precision of and optimizes sprites rendering;
* removes pits borders along (transparent) barriers;
* refines video modes suggestions;
* removes the sort-by-name option;
* converts the characters set of themes to full ISO 8859-1;
* retouches the themes graphics slightly;
* improves the terminology;
* reworks some internal aspects of missions and themes for easier development of expansions;
* fixes the handling of alphachannel-less sprites (this bug had no practical consequences because no theme used such kind of graphics);
* adds a new tutorial mission;
* updates and improves the user's manual;
* applies some other changes.

BOH owners can enjoy the update by downloading it for free from the DOWNLOADS page of the official website.
The demos have been updated to reflect the changes.

Enjoy!
