Use edit evaluated mesh when creating mesh for object in edit mode

Makes the result of object.to_mesh() and bpy.meshes.new_from_object()
to be the same as what is visible in the viewport.

This makes Cycles to respect modifiers enabled in edit mode, and should
also easy some scripter's work. The final render still needs some work,
which, maybe, will be about forcing objects out of editing modes.
