Gives all IPCs EAL by standard (#21622)

Gives all IPCs, including every subspecies, EAL as a free language. All
other slots are retained. Done with the accession of the synthetic lore
writer.

Rationale is primarily for industrials and baselines - i.e. all the
subspecies without three extra language slots. This means any
baseline/industrial originating from a multi-language origin (Jupiter,
Visegrad, Himeo, etc) can pick both of their origin's languages in
addition to EAL. Those from monolingual origins have a slot free for
flavour.

This does have the additional effect of giving shells and bishops five
possible languages in total - this should mean it's a lot more viable to
take sign language as these even if they originate from a multilingual
origin, which plays well into them primarily being service units.

Burzsia's fluff on not giving their units EAL will be modified wiki-side
if merged.
