* Jscompiler takes now env_typer + code instead of old blender type
* flattening env_blender in qmlcompilers (qmljs command line tool)
* inline the part about typing from the blender in qmlcompilers
The blender was still used only by qmljs which does not support
db constructions (used only for debug and tests of pure client code)
so it does not need to treat db constructions anymore.
