iqe_import: update to work in Blender 2.8

scurest commented 5 years ago

Hi.

iqe_import survived a huge number of Blender versions but 2.8 finally broke it :) This PR adds support for 2.8. I've tested this in 2.64, 2.79, and 2.80, and it works in all of them (but I only have a few files for testing so more testing would be nice).

Some other tiny enhancements:

Vertex colors now work (they were broken before because of a missing [i]), including RGBA colors in Blender versions that require RGB (most all of them before 2.8)
The imported model is placed at the 3D Cursor, rather than always the origin. If there is no armature, an empty is created for the meshes (consistent with a comment that said this happened). The imported objects are selected.
Importing works if the user was in Edit mode when they called the importer.

Oh, and I wasn't sure if I edited the right importer (are there three?).

Yes, there are three importers. I can barely remember the difference between iqe_import.py and iqe_import_two.py. I think (but don't quote me) that the _two importer is cleaned up and simplified because it only handles the textual IQE format, not having to cope with the binary IQM. The code is mostly the same or very similar, so your changes ought to be easy enough to port over to the other one.

iqe_import_simple.py only does static models, no armatures or weights custom attributes.
