BannerLetters

• Removed lore (There's still a little black number which is just there so banners with the same letter don't stack)

I'm going to make all this changeable in a config but I don't have time right now and just wanted to release a little fix so you don't need to edit the lore manually to remove the line "This is a banner created with BannerLetters"

-If you place a "&", "%" or "/" at the end of the line, an error shows up. Fixed in the up coming version.

If you have an idea for a new letter or how I could make a letter look better (for example the S) please tell me in the comments! :)
