Full glooptest support

To support the glooptest mod (successor of gloopores), define the
gloopores lump->dust grinding recipes if either of the mods is available.
(Formerly only "gloopores" was supported.)  Define kalite dust item,
which was previously missing.  Make gloop ingots grindable to dust as the
non-gloop ingots already are; incidentally refactor this to automatically
make ingots grindable whenever the ingot can be made by cooking dust.
Add textures for all the gloop dusts.  Do the "Steel"->"Iron" renaming
for glooptest-defined tools and items.
