Introduce a new, cross-browser HiDPI CSS @media rule to be used everywhere.

{{{
@media print,
  (-o-min-device-pixel-ratio: 5/4),
  (-webkit-min-device-pixel-ratio: 1.25),
  (min-resolution: 120dpi) {
}}}

Serve HiDPI graphics for printing, regardless of screen resolution.

Specify Opera's vendor-prefixed device pixel ratio property, for Opera desktop.

Specify a minimum Webkit device pixel ratio of 1.25 instead of 1.5, to serve
2x images to Android devices that are between 1 and 1.5x (like the Nexus 7).
Firefox and Opera will respond to 1.5x on these devices, but Chrome will not.

Specify min-resolution, which covers Firefox 19. Opera on Android also supports
min-resolution, but Opera Mini does not support dppx, so the dpi unit is used.

props iammattthomas for the exhaustive research.
props lessbloat for patching.

fixes #22238.

Media Library list table: Rename 'Attached to' to 'Uploaded to'.

In 3.5, we have chosen to de-emphasize the "attaching" part of the
post-attachment relationship. Existing functionality remains the same,
but UI emphasis is now placed on "parent" being where the item was
originally uploaded.

fixes #22439.

Pull the list of popular importers from WordPress.org.

These are the importers we suggest on import.php, prompting the user to
install the relevant plugin for the import they want to go through.

If the API is inaccessible, it falls back to a hard-coded list that should
be kept sync'd with the API with each major version of WordPress. This API
enables us to add new importers between releases, as they are completed or
if services gain quick adoption. As a last resort, we can also temporarily
disable importers that are broken (due to API changes, for example).

The importer currently returns English strings (which are then run through
translate() for existing strings), but the locale is passed to the API,
allowing us to ship translated strings if we wish to be adventurous.

props dllh for the assist.
