ofLog: fix module print when given empty string & add printf style function to log level classes
add example for instanced vboMesh drawing

This demonstrates how to use ofVboMesh::drawInstanced() using the programmable GL renderer and a matching shader.

It will draw 16384 instances of an ofBox primitive, spreading these out on a grid, extruding their height on the vertex shader using a depth texture, and animating along the x-axis, to make it a little more interesting.

Plenty of comments inline.
