All enum errors have (hopefully) been changed to a luax_enumerror, which has a
fixed error message. If additionally a list of valid options is passed, it
lists that in the error message. For every enum error with few options I've
implemented this using a getConstants call.
This solution has been designed specifically to reduce the number of template
instantiations (as I've been told that was a concern). All new template code
happens in places where there already was an instantiation of the relevant
StringMap. Of course there is still std::vector<std::string>...

I opted to remove the optional parameters altogether since they seemed oddly
out-of-place. They used to reset the values to defaults when not supplied, and
they also weren't returned by getAreaSpread(), so
setAreaSpread(getAreaSpread()) actually changed spread parameters.
The other option was to remove the separate getters/setters for
AreaSpreadIsRelativeDirection and AreaSpreadAngle, and fully rely on
setAreaSpread for these parameters, but the rest of the ParticleSystem API
tends to keep parameters separate.

2 new Particle System Distribution types:
borderellipse - spawns new particles around the border of an elllipse shape defined by dx,dy
borderrectangle - spawns new particles around the border of a rectangle shape defined by dx, dy
New functions:
getAreaSpreadAngle()
getAreaSpreadIsRelativeDirection()
setAreaSpreadAngle(angle in radians)
setAreaSpreadIsRelativeDirection(boolean)
setAreaSpread(distribution, x, y, (optional)angle, (optional)isRelativeDirection)
- angle - defaults 0. In radians the angle to rotate the entire area spread distribution
- isRelativeDirection - defaults false. When false, particles will travel in the direction defined by setDirection(). When true, particles will travel away from the center of the area spread shape
