ColoredGlowLib

Added a datafile so now it is possibile to save the color assigned to Entities/EntityTypes/in general (it also represents somewhat of a configuration file in the config/ folder but it's not advised to use it that way, i'll may write a wiki page to use it properly as one in the future)

Added a few more methods like hasEntityColor() and similar QOL additions (nothing that was impossibile to do before)

Removed a few debug printlns that i forgot

Now when an entity dies it's going to get rid of its color from the map/list contains it

Now the color of an entity is saved as an HEX string instead of Color object

Rewritten the rendering code to make it better & tidier

Fixed some bugs such as not being able to set a rainbow color using the command

Started to think how to make this mod compatibile server side too (Most likely will require to have it both on the server AND the client since the thing the rendering is done only clientside)
