Subject: [PATCH] Spell's get_description can now replace some words with value
 of it's properties. e.g. "%%cast_cast_time " (not the whitespace at the end)
 will be replaced to the value stored in cast_cast_time. This value can scaled
 with class level like %#cast_cast_time, and with character level like
 %$cast_cast_time. Also made get_description overrideabe from scripts. And
 bound text_translation_key.
