Timers should show NEGATIVE time after allotted time has expired

[bmorrissirromb]

In event timers that are integrated into ballots, the timer does not show how far PAST the allotted time a speech has gone. This is a problem because it makes it difficult to know if the speech is in the grace period or not.

Recommended fix: in RED, as a negative number, show how far past the grace period the timer is, if the timer expires
