Fix SViewFrustum::setFrom for OGL projection matrices. 

SViewFrustum::setFrom now sets the correct near clipping plane when the projection matrix doesn't use a target depth range of 0 to z, but for example -z to z.

--------------------------
Changes in 1.9 (not yet released)
- SViewFrustum::setFrom now sets the correct near clipping plane when the projection matrix doesn't use a target depth range of 0 to z, but for example -z to z. So OGL projections matrices can now also use it.
- Remove code to read boundingbox element in Collada reader as it's not in Collada specification.
- .dae/Collade reader now converts from Collada's right-handed to Irrlicht's left handed coordinate system (switching z to -z)
- Add irr::string::eraseTrailingFloatZeros to kick out trailing 0's for strings generated from floats.
