Spanish Translate for new Group/Chat/IM floaters and some general string fixed
Fix Issue 432: Radar Keeps Popping Up and side issue `I got still the window "An object owned by you ..."`

Unified key message sending to function send_keys_message()
Switched a few getBOOLs to CachedControls
Added RadarChatKeysStopAsking, and RadarChatKeysRequest as a three button notification so the user can decide to permanently say no.
Corrected RadarChatKeys description to be more accurate.
If we want to know if the radar is open, we check instanceExists, not getInstance.
Also enabled using the announce button when RadarChatKeys is false to announce keys, for manual updates.
