real demo

this project aims to make the (java edition) **demo** look like the **real game**! here are a few examples of what it does: > removes the time limit text! (no image for this one, how can i show it if i removed it, also the time limit will still be there) > changes all the names in chat to "itsnotalex5" (u can change it, idm, its in en_us.json)  > changes the menu up a bit to replicate the real one  > removes most of the warning when u enter ur world  also all of this only works for US english and i have no idea what even happens if u try this in the full game
