[Plib-devel] Changes to save ASE, save ASC and load PCX

[Wolfram K. <w_...@rz...>]

When a model contains selectors, the ASE and ASC writers now write out
all children. This is ther behaviour that other loaders had beforehand
already.

I reworked my loader of PCX textures. I would appreciate it if someone
tests the loader.

Bye bye,
Wolfram.
