Corrected all score-altering code to adjust an individual player's score.

Adjusted code that handles player lives to use the player object. Due to initialization timings, this means that lives do not update correctly anymore.
Revamped the killfeed to handle themes and multiple attackers.
Commented out susped/continue game because using them at the moment will break the game.
Created new utility library named "loveutils" that contains love-centric overloads and extender functions.
Refactored the player file to reflect their name in the objects array.
Restored world -1.
Added a mushroom to make the player small regardless of their state.

Added generic object filtering library.
Added more properties to world.
Made dummy gamemode object with an example of one of its potential responsibilities.
Added extremely dummied up damage class for future use.
