Standardize comparison when comparing builds

[frzyc]

There is a discrepancy between the current/colored comparison build in terms of "build result" vs "tc interface". We should seek to standardize this:
[current build number] [+/- compare build number]

This should make it so that regardless if you are comparing or not, the "white text" should show the "current build" value

Also, in the codebase, the DataContext are referred to as {data, oldData}, which is not be best naming, I'd recommend refactoring to {data, compareData} to ease this transition.
