return compile status after rebuild on render()
initialize m_refresh member variable
first working modelASSIMP3 plugin
avoid crash when drawing empty arrays
pass model data to VBO

also add a m_refresh bool to update VBO arrays
pass model data to VBO
Merge branch 'modelASSIMP3' of github.com:avilleret/Gem into modelASSIMP3

Conflicts:
	src/Geos/model.cpp
allow multiple inclusion of this file
add a Type to describe VBO data
don't pass array name but array array itself to copyArray
add a getVBOarray() method that return an array of VBOarray

VBOarray contains both data and VBO type
this is more optimized than string comparison
use the new getVBOayrray()
Merge remote-tracking branch 'avilleret/model_plugin'
renamed ASSIMP2 to ASSIMP3

seems to be a search-and-replace leftover
