Watchdog 1.7

Watchdog monitors Xcode and automatically cleans up stale cache files that prevent you from getting a good build. It will save you hours of aggravation dealing with a number of problems you might see including:

- Old images that you've replaced, still showing up in your app.

- The DerivedData folder growing continuously over time, often taking up 10 gigabytes of space.

- Constants/Defines not updating in the app after you've changed them in the code.

- Localization file changes not being seen.
