Improvements to effects: Release of Spaceships version 1.1.1

New version

I have now released version 1.1.1 of Spaceships which includes minor but important changes. These changes are to how effects are handled in relation to effect zones and collection of multiple of the same powerups.

Versions 1.1.0 and 1.1.1 are compatible both ways, so you can freely update the game without worrying about any compatibility breaking (though do expect slight changes in the server configs, keep reading to learn more).

Changelog

• Effect zones no longer override powerup effects. Now when you collect a powerup and move into an effect zone of that same effect, those two effects are now stacked together to produce an overall stronger effect. Previously, this would override the player's powerup effect and disadvantage the user.
• Effects can stack up. Suppose that the player collects two damage powerups at the same time. Assuming default settings, previously this resulted in a 1.5x multiplier to the player's damage for 60 seconds (compared to the usual 30 seconds for just a single powerup). Now, these effects get multiplied together so the player will get a 1.5² = 2.25x damage increase for the time both those effects are active (which is at most 30 seconds). The previous behaviour is still available but it must be configured explicitly (see flood.ron for how it's done).
• New config. I have added a new server config, flood.ron, which generates powerups and ammo crates as fast as things are currently supported (which is once per update).
• Other config changes. Now all powerups spawn in all configs. Previously some configs didn't spawn some types of powerups due to the previous behaviour of those powerups overriding the permanent effect. For example, slow.ron and fast.ron previously didn't spawn any speed powerups.
• Deprecation of min_time. This field in the effect zone is now deprecated. Right now it does nothing, but keeping this field in will error in future versions.
