Add separate events for local and global chat (#4683)

This commit adds two new events: GlobalChatEvent and LocalChatEvent,
which allow other plugin developers to know whether the message sent is
a global or local one and act accordingly. If either of those events is
cancelled, then the source event is cancelled too.

Since all chat-related events share the same structure, a new abstract
class ChatEvent is created with change made for LocalChatSpyEvent to use
it without breaking its API.
