Look and feel hotfixes post-splits implementation.

[Aaron Polhamus]

What's up @ruidovisual? I was going to text you but figured that this would be easier with a ticket. Splits is going great -- tests are passing and the frontend pulls up without any issues. In order of importance, here are some things I would like to nail before sending stockbets.io invites to a couple prospective partners/investors later this evening:

1. I broke the compound charts -- can you help me get them working again? I'll be super-responsive to whatever you need from the backend.
2. Chart labels are now posix time formatted -- would be great to get some datetime formatting on there
3. All the formatting in all the tables has been scrubbed -- we need to format percentages, currencies, and posix dates
4. When you select a stock the "last updated" timestamp isn't formatted anymore -- it just comes in as posix
5. For real-stakes game, the GameInfo component needs to have currency formatting for gameInfo.stakes

This is for the branch: https://github.com/aaronpolhamus/stock-bets/tree/debugging_splits
