Bump all library versions to latest.

I had to satisfy a new Om requirement that components implement IRender.
Signal running-total timeout with a :reset value.

The running-total channel type now receives a :reset keyword value when
it times out; previously, it would reset to 0, but then keep receiving 0
values on every timeout interval.
Add simple combo damage component to show running total.

Right now, this is a simple div; it will be styled soon. Displays
running total, which is stored in the life-counter-view state.
