Rework unit colors for readability

[Glamurio]

Several units & classes currently share the same color which hinders readability.

In an effort to keep the original preserved color, I've simple changed some shades of existing colors to keep their identity, but help distinguish them from one another. Good examples for this were Mage & Sorcerer as well as Conjurer & Mercenary.

• Rogues & Nukers
  • Rogues, red (#e91d39) -> red2 (#b3172d)
• Rangers & Healers
  • Rangers, green (#8bbf40) -> green2 (#598718)
• Mages & Enchanters
  • Enchanters, blue (#019bd6) -> blue3 (#7aa0ca)
• Warriors & Forcers
  • Forcers, yellow (#facf00) -> brown (#bb6f07)
• Conjurers & Swarmers
  • Swarmers, orange (#f07021) ->brown2 (#7e5419)
• Voiders & Cursers
  • Voiders, purple (#8e559e) -> purple2 (#63428c)

I've ensured to keep the naming scheme similar to the way existing colors had been named. Furthermore, I've ensured that all projectiles that reference old colors are updated to their respective new colors.

Additionally, the following units have had their colors changed to be more in-line with the rest of the unit colorization and reflect at least one of their classes at a glance:

• Sage (Nuker, Forcer)
  • purple (#8e559e) -> brown (#bb6f07)
• Cannoneer (Nuker, Ranger)
  • orange (#f07021) -> red (#e91d39)
