Add space for more warnings

[TristanDebrunner]

On the main screen, we only have space for a maximum of 6 warnings, but more are likely to be needed in some game situations.

Proposed Fix:
When there are more than six warnings to display, make the game info button as small as possible, and expand the warnings button. This means we can likely only fit the current game number, but we already have a secondary page dedicated to providing the full details. Also, this shrinking is likely to only happen later in a game, when the game details are much less likely to be needed.
