Port FBX module from commit 68013d23932688e57b489600f4517dd280edc464 Ports FBX module from 3.2 branch to 4.0 This is the only time the plugin will be updated from 3.2 and marks the final time we do this, from now on we will backport FBX to 3.2 with fixes. Changelog: - fixed crash importing files with buggy format (because of bad newlines in ASCII data, this is yet to be fixed fully) - fixed const correctness with C++/C version change - rewrote material handling to be simpler and better - ports from 3.2 to 4.0 the fbx importer

This stops using FBXPropertyTable as a pointer. The base object will inherit the property table, for every FBX object, if it doesn't exist it will be ignored. The previous code was dangerous and not simple to understand, this makes the code simpler and should result in no leaks with PropertyTable. Features/Fixes: Adds ability for multiple millions of polygons to be loaded. Fixes memory leaks with tokens Fixes memory leaks with property table Fixes loading some corrupt files Fixes meshes not having a unique name to the mesh node. Opens up loading for two more versions: 7100 and 7200, up to 2020. Preliminary support for Cinema4D files in parser now, before this was not possible it would cause memory corruption, which is gone now. FBXProperties not being pointers presented simpler challenges in the long run also, fixed a bunch of bugs.

Fix zero scaling and material mappings being mapped to wrong fields - fixes scale values of 0.0013 (det == 0.00004) not rendering, they should render even at small values, but not at zero like the editor grid plugin supplies zero exactly. - fixes node_3d_editor_plugin visibility bug when scale is zero - fix culling with small scaling values - which are still valid to be rendered like 0.00004 note: grid is still not fixed, it has det == 0 issues but this fixes one of them.
