Material to geometry improvements
Never clear materialGeometryMap, instead when needed to create a new
geometry for each material of each object, append the object name to
the material name.
This should allow to use 'lod' + 'merge' + 'don't merge materials' all
together.
Completed materials list export
It should work also when not merging the materials.
Used relative path for materials XML for better portability.
Should fix #7.
Added support for triggers
We use the timeline markers.
