BUG: River crashes dedicated server (fix inside)

When running a dedicated server a mission with a River object will cause the server to immediately crash in:

River::onAdd()

The problem ends up being in:

void River::_generateSegments()

which is called by:

void River::_generateSlices()

The exception occurs around the allocation of the VertexBuffer.

A simple solution to this is simply to check if the river is a server object prior to calling _generateSlices().

You could do this right in River::_generateSlices()itself or, as I chose to do, add this line to the end of void River::_generateSegments()

change

_generateVerts();

to

if(!isServerObject())
		_generateVerts();
