Centralized player chat management resource

[jlillis]

Is your feature request related to a problem? Please describe.
There are multiple onPlayerChat event handlers across multiple resources that implement the same or trivial functionality, such as:

• playercolors: hooks onPlayerChat to apply the player's nametag color to their name in chat
• freeroam: duplicates playercolor functionality and implements spam protections
• tdma: applies team colors to chat messages
• ctv: same as above
• assault: same as above

In the case of freeroam and playercolors, these handlers conflict with each other resulting in chat messages appearing twice (see #460).

The other cases are examples of duplicated functionality, which isn't ideal.

Describe the solution you'd like
Implement a new chatmanager resource with the following functionality, customizable via resource settings:

• Option to have player names appear in their nametag color
• Option to have player names appear in their team's color
• Anti-spam options, with integrations for admin and admin2
• Other options as recommended

Describe alternatives you've considered
Changes could be made within mtasa-blue to implement player and team name colors in chat by default.
