Translate FireRed ability names where they are shown

Species, move, item and trainer names reach a translation mod through registries, but nothing renames abilities: battle messages ("<POKéMON>'s <ability> prevents ...") and the summary page printed the ROM's English name whatever the language.

Abilities.name and the summary's ability line now pass the name through Strings(), keyed by the cart's English name ("SPEED BOOST", "COMPOUNDEYES"). The identifiers the battle code compares (SPEED_BOOST) and the description lookup are unchanged.
