Monster 'Evilrip' integrated, new creature sounds in SVN

The recently contributed monster by tidbit baptized as Evilrip, a two legged, armless, reptile-like winged fury is now haunting the halls of Chaos Mazes! The other monsters previously added (Plant'o'bite and Scorp'o'holder) and Evilrip recently have found the Fountain of Tones so now they have their unique threatening voice... the poor adventurers that get near to them will hardly forget the sonic experience! ;-)
PS: Recent reports tell that boarman tribes are hit by economic issues, so at some populations the citizens started to build huts instead of the well built, but expensive and resource eating wooden houses. Although it's clear that this new technological unit (invented by tidbit) might catalyze their expansive politics, if they ever had such.
