Updated chatview texts

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)
