In rBA6aa8e130eff59059886e203ff95221609f63b222 all occurrences
of "lamp" where replaced with "light" which also accidentally
renamed "clamp" to "clight". In case of the x3d importer and
object carver add-on this broke some functionality. This
commit fixes the names to match the use the correct properties
of the Python API and use semantically correct names for other
add-on where the renaming didn't cause functional changes.

Mainly search-and-replace approach.
Tested the enabled-by-default export/import addons. Seems to work with
an exception of X3D which is still referencing Blender Internal material
properties.
