Lots of improvements to value displays:

- use mixins instead of include - new settings: displayCurrency and localCurrency that work in tandem to build value displays - cleanup/simplify utils functions - simpler/better options UI for currency settings - most "value displays" use a default mixin "+valueDisplay" and a few special-case value displays use a new "+valueDisplaySpecial" to simplify happy-flow logic And: - move "fun" items into separate file (btc.js is getting ridiculous) - new currencies.js file for global currency data - tweak header nav styles
