[TF2] Exploded Caber uses incorrect texture

[condor00fr]

The Ullapool caber has a texture meant to be used after it exploded, but for some strange reasons isn't actually used.

It's actually pretty easy to fix. In the model "c_caber_exploded" the material named "c_caber" and to fix the issue all need to be done is to just rename the "c_caber" to "c_caber exploded"
