Fixing up a few things

| Projectiles
+ Made them not collide with the player

| Timer
+ Changed the whole timer class - Destroy with a time is slow and should
be avoided

| Store Script
Removed the gamemanager variable as it's not needed. GameMananger.gm
suffices

| To work on tomorrow
+ Melee weapons
+ A system to allow for multiple weapons
+ Different Goblins (Shoot and hitting)
