Adjust trap detection formula

Goodbye magic 8.6 breakpoint (you will be mourned by some, I am sure).
Instead, 8.6 provides a roughly 88% chance of detection, scaling
up to ~99% at 27 skill. Detection chances at lower skill at similar
to present (or slightly more generous). Ash will still provide 100%
detection with a modest amount of piety and/or skill, however.
Make swiftness actually cut your trap detection chance in half

For a while now it has not affected detection of traps at close
range, making the bit of its description about it making you more
likely to 'blunder into traps' rather incorrect.

Add formatting fixes.
Properly use mons_make_god_gift() for directly Fedhas-created plant allies.

Also, ensure that attitude change attempts work properly on
ballistomycetes evolved from floor mold, and experience is not rewarded
for any directly Fedhas-created plant allies.
Rename a variable, for clarity.
Remove unneeded setting of the attitude change attempt flag for hostile spores.
Properly mark hostile Fedhas spores as giving no experience.
