Load Powers.cfg at world boot

PowerParser loads Powers.cfg into PowerTemplate._powers. The 22 header
fields are named after the client loader's error messages (0x56E410);
ACTION= lines keep trains, duration, curve and stack fields; prereqs,
curves, flags, messages and CONDITION blocks are kept. Keys compare
case-insensitively, as in the client. Four keys the client ignores
(APPLYDAMAGESELF=, APPLYEFFECTCASTER=, APPLYEFFECTTARGET= and a
POWEREND= typo) are skipped; any other unknown key fails the load.

Numbers are read like the client's atoi/atof with a warning when a
token isn't clean: PRL-033 init time "2.9.0" -> 2.9 and SGE-001
precision "10.0" -> 10, which matches the DB. Ten EQPREREQ lines end
without a required flag, which the client reads as 0.

Needs the fixed Powers.cfg (SRDX-DB header had "SPELL 15 Unknown"
pasted twice; fixed in MBDATA, findings section 6).
