Allow the user to drag faster
defer most processing until after delay
Make the window the holder
Prevent extensions from using window.open() as a quick way to show the user
general, untrusted web content. Throw exception pointing out the 'right'
safe API to use. Still allows file: URLs and relative paths (which are by
definition file: too, and used by Debug > Run Tests).
Allow window.open() with about:blank too (one extenion is using this, and
it's generally useful for programmatically generated UI)

Created index.html in Dutch language

Index.html file for "Getting started" ("Aan de slag")
Cleanups to status bar language-switcher:
* Make LanguageManager the official public API that is used to set per-file
overrides, rather than proxying through Document objects - remove Document.setLanguageOverride()
* Clear path overrides when switching projects, so it's more obvious that
it's not something that gets persisted across sessions
* Simplify how JS Code Hints listen for language updates: remove dependency
on "currentDocumentLanguageChanged" event; remove unneeded extra 'if' tests
Add "Set as Default" menu item to status bar language switcher -- adds a
permanent file extension mapping to preferences, based on the current
file's path-specific language override (if any) and its file extension.
* Gray out status-bar language switcher's "Set as Default" item if the doc's
current language is already the default (i.e. there's no path-specific override).

DropdownButton changes:
* Support disabled items
* Fix bug #8433 (Page Up/Down work oddly) - Only wrap around to other end
of list when using arrow keys. Page Up/Down 'stick' at start/end of list
instead (so they will act like Home/End when there's no scrollbar).
* Add Home/End key support
handle live preview for docs not in working set
allow .xhtml files for live preview
