Did some major refactoring in addition to two new 'features':

Translations (preliminary):

• Added translator which allows most strings to be changed/translated through the 'translations.yml' file in the plugins folder
• This is very much a work in progress - please don't start translating anything (idk why anyone would but I don't like wasting people's time)

Holograms and Placeholders:

• Holograms are all provided internally (though I do plan to eventually allow them to use another plugin instead if desired)
• Placeholders also all managed internally (with plans to integrate with PlaceholderAPI)
• Holograms are created by using the Admin GUI to create an item that places it
