Ban based notification to other online moderators is the first form implemented by this PR.

With this update a new chat history definition is added on a per
room bases which allows operators to specify the number of chat
messages to store and present to the user on join.  Please see
the sample ini for room definitions.

Previously would not open the client if the window was minimized.
Added the same popup fix for mentions

+ Can be used for setting client size and closing the client.

Will expand on by sending client alerts to the tray.

Updated to push message notifactions to the toolbar

Preview image:

Added setting to enable/disable message popups

Added functionality

+ updated popup message and translation
+ Double clicking tray icon will now bring up the app/minimize it
+ can now be alerted of mentions
+ added setting to set if you want mentions on desktop
+ clicking mention message will take you to the main chat
+ added translations for icon menu
+ removed maximize/minimize/restore from menu, not needed.

Added disconnect

+ Disconnects any previous message slots/signals from the system icon
message bubble

This is enforcing a new client wide color scheme.
RULES
+ Green = Major server message (Welcome to chat room, change phase...)
+ Red = Minor server message (timestamps, game actions...)
+ Blue = Key word
+ Blue with modifier (underline/italics) = Keyword that can be
interacted with.
+ Black = User text

+ key numbers are now blue. player drew X cards, looks at the top X
cards, places X counters on . . . and so on.
+ card names are now italic (different from urls now)

I did have the player names set to blue also, but it felt like too much.

Player names in phase change are blue

Updates

+ Updated username colors in phases to match other areas of client

Small update

+ Made server message in chat room bold
+ made User names in chat/pm match the weight of in-game (consistancy)

Additionally, use the same name for “private chat“ in all menus (we had
“personal talk” and “direct chat“ before)

+ adds client wide continuity
+ one day we might have multiuser pms
+ I use it when greeting users who pm me: "hello @username!"

As suggest by Daenyth in #185

context menu for a message sender's name in chat; also display the user level icon next to the name; minor consistency and type-safety changes
