Eternal Summer TL Patch 0.75

Game Link: RJ406483
Game Version: Release 1.5

The school+library area is close to being fully translated. Dealt with the parts I find either too wordy (books in the library), or annoying to work on (wrestling event -- too many npcs speaking, some difficult to translate lines). It's a huge weight off my shoulders, honestly.
