Additions / changes

Hey! Here are the textures that were in the John Smith Legacy x64 folder i've had for a while that weren't in the repository already plus a couple extra textures that i've done which include the endstone block texture and the brick, nether brick and egg item textures. I've also replaced the record_wait.png texture to the original texture which matches the colour of the x32 pack and made some changes to the heart icons in icons.png as well as some minor changes to name_tag.png.
