Weapons should work framerate independent

[xchrdw]

idea: Gun::fireAtPoint() should spawn bullets and forward them for (currentTime - lastShot - coolDownTime). Then update lastShot = lastShot + coolDownTime.
This should only happen if the player was fireing in the last frame!
Sound only needs to played once

Another idea: #542 as my proposed solution for everything

• GameElements would be a baseclass of Weapon and Bullet.
• GameElement::updateFrequency() is the weapons frequency, so Weapon::update() is called for every bullet that needs to be spawned
• GameElements have their own clock, progressed on GameElement::update(), and Bullets will be spawned with the timestamp the clock of the Weapon has when it fires that particular bullet.

The effect would be that bullets indeed would be spawned on the same position, but because their clocks have different "delays" on the next frame, they would be moved different distances.

This may sound complicated but I think once the base-architecture (=GameElement) is implemented, everything will be much easier.

I have quite some ideas for this that I will present tomorrow.

Have we discussed @mrzzzrm proposal yet?

No, I'm still developing it (=the idea). Hope to introduce basics of it when doing #564
