Patch 1.06 - Various small changes

- Fixed issue where enemy gatling canons were shooting the wrong color of bullet.
- Adjusted pathfinding. Units should no longer hug walls so closely
- Enemy minigunners should now play their death animation rather than immediately disappearing into the void
- Bunker build time increased by .5 seconds.
- Hero hunters and flag hunters will now stop a little short of an enemy target, so that they don't go right on top of them. Also if too close to target, they will attempt to back away.
- Level 1 changes: Lots of feedback saying this level is a bit slow, and you have to wait too much on the workers. Basically it can get a bit boring after clearing out the enemy bases (less spawns when those are destroyed). The following changes have been made. The preparation timer is shorter, and the enemy bases have some soldiers defending them whereas they didn't before. This will make it harder to take the bases out. The escort will also spawn faster now. In total I've cut about 4 minutes from gameplay time off this mission.
- Fixed the rocket and sand bag cooldown lengths on heroes.
- When you spawn as a hero there is a time limit before you are allowed to manually despawn. This was initially put in place to prevent players from despawning and immediately respawning as that hero to refresh their cooldowns and ammo. Instead you can now manually despawn 1 second after spawning (kept a minimum to prevent spawning the same hero that is currently playing its despawn animation). Now if you despawn then respawn as the same hero within 10 seconds, their cooldowns and ammo will be the same as when they despawned. If you wait more than ten seconds, they will have full ammo, and their abilities will be off cooldown (including all grenade charges for Hunter). This will also help with the issue if you forget to move your blue flag before spawning, you'll be able to despawn after only 1 second.
