github pull request #102 - Popeye vs Fixed_abil

Fixes #102

This is a simplified version of the code in pull request #102,
which replaces "You feel like Popeye!" with "You feel like {Olive
Oyl or Bluto}!" if eating spinach fails to provide a strength gain.
I think you should still feel like Popeye if the lack of gain is
due to already being at maximum, so I left out the change to make
gainstr() return a value which indicates whether a change took place.

Unfortunately, if you're both already at maximum and have attribute
changes suppressed by Fixed_abil, the latter overrides and you'll
feel like Olive Oyl or Bluto.  I think that situation is too obscure
to bother with the complexity of figuring out if you're at maximum
for the purpose of a silly message.
