Boss HP scaling command implementation

[Strife (strife-mod)]

Summary

Implementation of /bosshp command to allow players changing coop difficulty by adding custom boss HP scaling formula:
targetScaling = scaling + scaling * (areaPlayers - 1)

Original scaling formula is retained and is used by default if /bosshp command has not been used:
targetScaling = 1 + scaling * (areaPlayers - 1)

Constant 1.5f has been replaced by scaling variable used by both formulas.

Two variables has been added to Config class to define scaling modifier and indicate if custom scaling is active. If these variables would be exposed for server owner in .txt or .json file, it could be used to change default boss HP scaling to their preferences.

Method CustomScaling(int scale) has percentage of boss HP as parameter and shows messages if Player is not MasterClient or invalid parameter has been used in command.

Example

Original formula:
targetScaling = 1 + scaling * (areaPlayers - 1)

Players	Scaling	Boss HP
1	1.5	100%
2	1.5	250%
3	1.5	400%
4	1.5	550%

Custom scaling formula:
targetScaling = scaling + scaling * (areaPlayers - 1)

Players	Scaling	Boss HP
1	0.5	50%
1	1.0	100%
1	1.5	150%
2	0.5	100%
2	1.0	200%
2	1.5	300%
3	0.5	150%
3	1.0	300%
3	1.5	450%

Problems & improvements

• Players need to use /bosshp command every time they join server, it will be reset to default scaling when session ends
• After using /bosshp command it's not possible to change scaling formula to original scaling.
