Better console logs for some errors:
- Improved error reporting for swallowed exceptions in ProjectModel, AppInit,
FileTreeView (show stack and actual exception message)
- Clearer error message when extensions fail to load due to requiring a
non-existent module

Additional small cleanups:
- Fix ThemeSettings dropdown change listener so it is properly specific
- Docs improvements for tree & working set decorators
- Several other docs tweaks

  * Mark DocumentManager's old events as deprecated *before* extensions have a chance to register for them. Clean up docs. * Fix $() shim warning: it was incorrectly flagging r.js-concatenated extensions as core code, since the whole path prefix is wiped off in that case. Unfortunately the same is true of core code in production builds, making the two indistinguishable. So: only flag as core code when the path indicates a dev build
