This additionally: * Makes all copyright notices identical aside from the starting year for Wesnoth-specific source files. Files not included: mariadbpp, lua, spirit po, xbrz, and bcrypt (crypt_blowfish). * Removes all attribution from the files, since the vast majority of them are outdated or seemingly just outright incorrect. For example, I would guess that Dave is no longer the sole author of the majority of Wesnoth's current code.
