Add -fail messages for harsh sun, heavy rain, strong winds

All new messages are from the textdump.

Currently, I'm implementing a `[weather]` tag to check for weather failures 
and just blank for the Fire/Water negation. I can probably move it somewhere 
else though, to make it more clear (put it in `-activate`, maybe?)

Strong Winds' message is an `-activate` tag instead of `-ability` because it 
activates even if the Delta Stream Pokemon has been hit by Gastro Acid
