SuperBMD v2.4.0.1 Pre-Release

Changelog:

• Fixed an issue with skeleton root searching in some models where it would detect two skeleton roots and refuse to convert the model to bmd. This fixes issue #38
• When mesh sorting isn't possible due to "amount of meshes not the same as amount of objects", SuperBMD now will simply not sort instead of throwing an error. This fixes #39 (and numerous counts of this issue having been reported to me on Discord. Issue seems to be due to how new versions of Blender export .dae). The old behavior of throwing an exception can be brought back by the use of a new argument --sort_strict.
