Fixing up file loading so that objects with levels of details properly have their levels of details brought with them when linked or appended.

Moving some code out of rna_object.c to object.c for updating the level of detail distance.

Using NC_OBJECT|ND_LOD for notifications instead of NC_LOD.

Simplifying the usage of BKE_object_lod_meshob_get and BKE_object_lod_matob_get, and cleaning up the code lod code in object.c.

Expanding abbreviations used in some level of detail operator names.

Removing the need to have a LodLevel for every object by adding a few checks for special cases.

Changing the label for "Setup Level of Details By Name" to "Setup Levels of Detail By Name"

Rewriting copy_object_lod to use BLI_duplicatelist.

Renaming BKE_object_lod_check to BKE_object_lod_is_usable to make what is being checked more clear.
