RC Plane Challenge: Switch to using fake crates only

Speed Shoppa Mission Framework for Hedgewars

This is a simple library intended to make setting up simple training missions a trivial
task. The library has been created to reduce redundancy in Lua scripts.

The framework generates complete and fully Speed Shoppa missions by just
one function call.

The missions generated by this script are all the same:
- The player will get a team with a single hedgehog.
- The team gets infinite ropes.
- A fixed set of crates will spawn at predefined positions.
- The mission ends successfully when all crates have been collected
- The mission ends unsuccessfully when the time runs out or the hedgehog dies
- When the mission ends, the time it took to finish the mission is shown

To use this library, you first have to load it and to call SpeedShoppaMission once with
the appropriate parameters. Really, that’s all!
See the comment of SpeedShoppaMission for a specification of all parameters.

SpeedShoppaMission(params)

This function sets up the *entire* mission and needs one argument: params.
The argument “params” is a table containing fields which describe the training mission.
	mandatory fields:
	- map:			the name of the map to be used
	- theme:		the name of the theme (does not need to be a standalone theme)
	- time:			the time limit in milliseconds
	- crates:		The coordinates of where the crates will be spawned.
				It is a table containing tables containing coordinates of format
				{ x=value, y=value }. Example:
					crates = {
						{ x = 324, y = 43 },
						{ x = 123, y = 56 },
						{ x = 6, y = 0 },
					}
				There must be at least 1 crate.

	optional fields:
	- missionTitle:		the name of the mission (optional but highly recommended) (default: "Speed Shoppa")
	- hogHat:		hat of the hedgehog (default: "NoHat")
	- hogName:		name of the hedgehog (default: "Roper")
	- teamName:		name of the hedgehog’s team (default: "Shoppers")
	- teamGrave:		name of the hedgehog’s grave (default: "Statue")
	- teamFlag:		name of the team’s flag (default: "cm_shoppa")
	- clanColor:		color of the (only) clan (default: 0xFF0204, which is a red tone)
	- goalText:		A short string explaining the goal of the mission
				(default: "Use your rope to collect all crates as fast as possible.")
	- faceLeft:		If true, the hog faces to the left initially, if false, it faces to the right.
				(default: false (=right))
	- crateType		Specify the type of crate (this has no gameplay effect), pick one of
				"ammo", "utility", "health". Default: "ammo"
	- extra_onGameStart:	A function which is called at the end of this script's onGameStart. It takes no parameters.
				You could use this to spawn additional gears like girders or mines.
	- extra_onGameInit:	A function which is called at the end of this script's onGameInit.
