Fixed: Generate LODs no longer fails with a Python error on a mesh that has shape keys. Such a mesh is skipped and named with the reason, and nothing is left behind on it.

Fixed: an object that has a parent no longer jumps when its LODs are generated, and Remove LODs puts the parent back. If you moved the LOD group after Generate, Remove LODs keeps the object where the group took it (an animated object follows its own animation again).

Fixed: Remove LODs deletes only the objects MobileReady created. Before, it deleted any object whose name matched name_LOD1, name_LOD2 and so on, including your own. Your own copies (Shift+D) of the object or of a level are not deleted and not moved.

Fixed: the mesh datablock is no longer renamed, also when two objects share one mesh, and Remove LODs gives the object its own name back, also when a name_LOD0 of yours already existed.

Fixed: Remove LODs on a chain linked from another file, and Generate LODs in Edit Mode, are refused with the reason instead of a Python error.

Generate LODs on an object that already has a chain, or on a LOD itself, is refused with the reason instead of nesting a second chain. Decimate no longer leaves loose vertices in the levels.

The status bar reports the triangles every level ended with, and says when a budget was not reached or the mesh was already under it.

Chains made by 1.0.0 carry no marks and are not removed by Remove LODs, which says so whether the object, a level or the empty is selected; delete their LOD objects by hand.
