updated Dashboard colors

added color coding to “Recent games” listing.
Blue = Arena win
Orange = Arena Loss
Green = Const. win
Red = Const. loss

Also added in class color support as label-classname for future use.
undid oops of ignoring gitignore
color coded dashboard "best arena" to match class color

note: the Rogue and Priest colors were altered for readability. Priest
is grey instead of black and Rogue is golden instead of raw yellow.
