ServerRPCStore ticking

[nataliethistime]

The lack of ServerRPCStore ticking has caused issues with the following things:

• Essentia boost countdowns
• Showing promotions
• Showing server version in about window

There are a few solutions to this:

• Make things that need to count listen to the Ticker store. (However, this would mean that the view needs to be responsible for something that it shouldn't).
• Make stores handle getInitialState properly. As in if there's data in the store return that, rather than the initial state.
• Put the server clock back. (I prefer this one because it makes components using the server clock pure again)

PS: I don't think the performance gain from not ticking the clock is worth much (if anything).
