Implement a proper gun fire-rate mechanism

Browse Source 
There is now a `Weapon` component which is just a timer for the gun's
fire rate. It is ticked every frame, clamping at the "ready" state (0
time remaining).

The ship spawns with this thing, and the `input_ship_shoot` system has
been updated to use it.
