Remove calls to most goog.* functions defined in Closure.
Move watchdog.* objects into the apps_dev_tool namespace.

Continue the migration away from closure by using cr.define to export
the items into the proper namespace.  Since this requires adding an
extra level of indentation to the code, fix up line wraps where needed.
Also fix up comments that refer to "watchdog".
Move watchdog JavaScript files into the main js/ directory and drop prefix.
Add copyright statement to the activity*.js files.
Delete the Closure Library.  It is no longer needed.
Comment cleanups suggested by p-march.
Prefix type names with activityLogPrivate in comments where appropriate.
Merge remote-tracking branch 'origin/master' into closure
