Admin: Raw text announcements with sound

[BasedUser]

Description

Admins currently have 2 ways to announce things - "station" announcements and server announcements. This is simply inadequate for events, because some people (i'm looking at you Corvax and DS14) would really want to announce with custom tags and everything.
A "raw" announcement would fill the niche where event masters need to do their work, and would enable them to do it without using SCSI.

What needs to be done

I propose to extend AdminAnnounceEui to have a third parameter, AdminAnnounceType.Raw - wrapping around one of the ChatManager SendToX functions, such that these optional(ly codable) constraints are satisfied, in priority:

• An optional parent is defined - descendants of this entity will get the announcement. If set to EntityUid.Invalid/left unchecked, everyone will receive the message.
• An optional sound FILE is defined - what will play on the announcement, or nothing if unchecked. Volume in a separate box, null string is 0.
• An optional color override is defined, otherwise null.

Also, adapt the .xaml.cs for it.
