Kanji Glossary Added

I added a new page to the site: Kanji Glossary. I have found that most English-speaking players (myself included) don't know kanji well, and when doing things like trying to look for items online, the search often comes up limited or empty. I hope that having these kanji available in one list will prove helpful. The terms listed are both general shamisen terminology and also terms that are important to jiuta. I will be updating the list periodically.
