v0.3.0: Movement and melee

I've had a bit of a lull in coursework, so I thought I would give this project some love. I managed to swap out the movement system to one using the character controller system. (Previously, I was using a janky ray-cast system.) Not getting stuck on geometry makes for a much smoother experience, I'm finding. Definitely helps you to focus on the enemies and the action.

I've also implemented a simple melee system. Right now it one-shots enemies, but I'll likely make the damage more nuanced in the future. It at least gives you some options if you're out of ammo! I also added loot drops on dead enemies, which should make the game a little more forgiving if you don't happen upon random loot.

So, changes:

• Reworked character movement to character controller: much smoother.
• Basic melee system is in place. Press "v" to use it.
• Health and ammo drop on dead enemies.
• More health and ammo drops in general.
• Start with 5 spare magazines rather than 3.

For the next patch, I'd like to overhaul the weapons system, improve the settings menu, and hopefully add randomized rewards for the different paths you take. This will hopefully give you something to think about when deciding where to go, and to plan your weapon/ammo management accordingly. Ultimately, I'd love to reach the point where you really have to think about your build, as you do in the best rogue-lites.
