Highlight Roles

This addon highlights words of interest by changing their color in chat and making them all uppercase.
Technically, this could be used to highlight any word you like but I made this specifically to highlight roles in the LFG chat for burning crusade classic. All configuration is done inside the `HighlightRoles.lua` file.

By default it highlights the following:

• "healers", "healer", "heal", "healz" -> HEALERS HEALER HEAL HEALZ
• "tanks", "tank" -> TANKS TANK
• "dps" -> DPS
