Soft Body rest length

[GoogleCodeExporter]

Just made a quick patch for btSoftBody to allow the modification
of the rest length of the links during simulation (mostly used
for ropes I guess but works with any softbody)
There's a new member variable in btSoftBody called m_restLength, which is
basically a ratio of the original distance between the 2 nodes
and the final length is calculated :
 m_rl = initial_length * m_restLength;

I've been playing around with it for a bit and seems to work great, also
takes into account the deactivation of soft bodies.

Cheers
Francois
