Free Coins!

- restricted coins to only spawn from players, not other entities

- coins can no longer be gained from dead bodies in the death animation

- coins no longer spawn when an entity is hit while "invulnerable" (flashing red after previous hit)

- added coinbos

 * if you get a combo (hit a player multiple times in rapid succession), more coins will spawn

 * each hit in a combo applies a x2 multiplier to combo hits, up until x8

 * a hit must be within 1.75 seconds of a previous hit in order to count as a combo

 * combos are not restricted by player, you can hit multiple players to continue your combo

- coins are now added up and displayed as a score

 * your score resets on a per-world basis, meaning on most minigame servers it will reset after each game

- added coin HUD

 * displays your current number of coins

 * displays your highest per-world score since you started your game

 * displays the total amount of coins you've earned total since you started your game

- added coinfiguration menu

 * added option to hide coin HUD

 * added option to simplify the coin HUD to only show your current score

 * added option to show or hide the descriptive text next to HUD icons

 * added X and Y options to adjust the position of the coin HUD

 * added option to only render 1 coin regardless of current multiplier (to help with lag)

- thought I added support for the Replay Mod... then realized it was still broken :,(. Maybe another time.

Note: re-uploaded because I realized 0.75 seconds to continue a combo is way too short.
