Merge async-createFileSystem() API change into in-browser fs branch...

Merge branch 'glenn/file-system' into pflynn/in-browser-file-system

* glenn/file-system: (56 commits)
  Change FileSystemManager.createFileSystem() to be async -- allowing filesystem impls time to seed any required initial data, or go through authentication workflows.
  Fix incorrect JSDoc parameter name.
  Updated by ALF automation.
  Update Tern and Acorn to the latest
  Change decompress-zip to the release
  Remove methods from eports
  Fix minor nit
  Added quick-edit.png for Finnish translation
  Find in Files title update
  restore handleWideResults property
  Deprecate FileUtils.getFilenameExtension() (which includes leading "."), introduce new FileUtils.getFileExtension() (which excludes it). Fixes bug #5365.
  Clean up
  Fix #5362 (HTML menu z-index vs. bottom-panel).
  simplify fix by assuming intent is to type (not insert hint)
  Code review cleanups
  Expose code inspection providers for the extensions.
  Update to decompress-zip that includes fix for our issue.
  Code review: use more consts in Find; remove unneeded single-tickmark API
  hasNativeMenus param code cleanup
  code cleanup
  ...
